sorry, no - but i would avoid buying one from canadian tire, sear's, or other general department store. pony up the money and get one from somewhere like the fitness depot.
give it a run in the store - not just a quick few steps, but an actual five or ten minute workout. that will bring up issues you won't notice from a quick dash on and off.
make sure the handles are comfortable for you to reach - you're not stretching or ducking to reach them comfortably. joints should be solid and there should be no metal-on-metal contact in moving parts.
if you can get the one with the metal contact plates to register your
heart rate, it's more convenient than the chest strap, but sometimes when you heat up, the plates can't register you any more. if you have two options, one with contact plates only and one with both plates and strap, get the second.
when you stride on the machine, it should feel solid and stable - some of the lesser quality models have an unstable tippy feel or they actually rock from side to side.
that's about all i can think of - not much use, but i hope it helps a little.
