Weighted vests

[mikeygone1]

I am looking into using a weighted vest for my workouts. I want to use it mainly for running but also for pull ups, dips and push ups. I would like one that fits well towards the top of my body so I could also use it for situps. I found one on the internet that was 20lbs for $135 but that is a little steep for me. Does anyone use these and where would be a good place to buy one?
Here is a link to the one I was looking at
