In my opinion, the soloflex is a good gym, in some ways better than bowflex etc. They all have strenghts and weaknesses.
(I'm posting a separate topic comparing them because I have seen a lot of disinformation mostly from soloflex haters...)
I am also considering buying a bowflex (or Crossbow, can't decide which).
Briefly, the soloflex has the following ADVANTAGES over bowflex:
1. Easier to assemble! I don't care what anyone says, cable machines are a pain to operate (and assemble!). I don't know about the bowflex, but from what I have read, the Weider crossbow is a nightmare to assemble. The soloflex has only two main parts to its frame and you assembe it with ONE BOLT!
Everything about the soloflex is EASIER than cable machines.
2. Easier to use! Again, cable machines require MORE work between exercises than the soloflex. Having to rearrange the cables to add the leg attachments, etc.. for example take more work and time than the soloflex.
3. Freeweight adaptable. For those who complain about the negative resisitance of soloflex vs. freeweights, well you can easily add freeweights to the soloflex.. you can't with the bowflex. Basically, the Soloflex is more more like traditional weightlifting than the bow/cable machines. You can't even do a real leg press or squat on the bow machines! ON the soloflex, it is just like freeweights, with the added advantage that you don't need a spottter.
Furthermore, with the soloflex you can get a LOT MORE resistance than with the bow machines. While the bowflex comes with only 210 lbs of resistnace which you can upgreade (for more $$$), the soloflex comes WITH 425 lbs of weightstraps! PLUS you can add 500 lbs of weights for a total of over 900 lbs!
I would think the soloflex would be better for SERIOUS weightlifters as well of folks who just want to tone up.
Also, unlike the bowflex, you can do free
body exercises (pull ups,
dips,
incline sit ups, etc.)
4. WELL MADE. The soloflex is EXPENSIVE yes. But it is well made.. much better quality than the bow machines. HEAVY steel, not cheap crap. The soloflex is so simple and well designed, it could easily sell like crazy against the other machines.. if the price were dropped.
5. Great Customer support. Soloflex still has great customer support (it may only be one person working out of their house now, I dont know

But I have never had any problems getting help from them. Even when one of my straps broke (the only one that breaks is the small 2.5 lb one) they have replaced them immediately, no questions.
NEGATIVES
There are a few negatives with the soloflex, but they are minor in my opinion:
1. Price. It really is over priced even though it is well made. Especially since they stopped doing all those TV commercials, I would think they could drop the price now. But, the bowflex is even more overpriced! Which is why I've considered getting a crossbow.. but I'm not sure it is well made.. seen complaints about missing parts, etc... and poor customer support.
2. Weightstraps can break... The straps were a revolutionary idea at the time.. they do the same job as freeweights, though some argue the negative resistance is not as good (but like I said, you can add freeweights if you want). However, these bands are made of heavy rubber, but the small ones can break. The only one that has broke on me is the 2.5 lb one, which is very thin and probably not needed. They started making them for people who needed something less than 5 lbs increments.. but really 5 lbs is small enough for most people.. But, they do replace the straps if one does break.. but since they may not be in business forver, I bought a box of extra straps to last me..
3. Pulls downs.. no freeweight adaptability. While you can add freeweights to the push up exercies, there's no way to add weight to the pull down exercies... here's where the bowflex has an advantage I think... you can get some better pull down resistance...
Now, I have been tempted by the bowflex (maybe the weider crossbow since it is cheaper) mainly because the do some exercies you can't do on the soloflex, but most of those can be done with dumbells, so I'm not sure they are worth the price.
MOST of the bowflex exercies can be done with a (cheaper) set of dumbells!
I do like the rowing exercises on the bowflex and crossbow...
but is that worth $1,000 (bowflex) or $500 (crossbow) ?
BOWFLEX/CROSSBOW
I don't have either of these yet though I'm thinking of getting one of them, but they also seem to have some advantages and disadvantages:
1. Resistance.. from what I've read, the resistance of the bows is not as good as weights, and varies. On the soloflex you can make up for this problem by adding some freeweights, you can't on the bow machines. The bowflex only comes with 210 lbs of resistnace, the soloflex comes with 425 and you can double that with freeweights.
2. OVERPRICED/INCOMPLETE
The standard bowlfex costs $999, and does not include the leg attachment or the lap pull down attachment. You can do pulldown exercies with the basic soloflex w ithout buying any attachments. Like the soloflex, the bowflex is also overpriced.. $1000 is way too much, especially when you have to pay extra to get the pull down attachment and add the resistance of the soloflex! So even if you were going to buy one of these new, the soloflex is still a better deal.
Whether you buy a soloflex or a bowflex, you will spend too much money if you buy one new, it is better to get one used.. I got my solofelx for $100, but I have spend about $500 to get attachments and extra set of weightstraps, and I bought their dumbell set and weights. Still, it was cheaper than a bowflex!
