I used to have one and didn't like it: non-segmented foam and pretty bulky. If you're looking for a CGA JP vest, CellBlock is a much better vest, IMO. Some people say the O'Neill Law is the best CGA vest of all. They're both more than $50 though.. This place got some sweet vests for around $50: http://www.evogear.com/outlet_results.aspx?bni=1453
I got the LF Team Comp vest from them and they have great customer service. The Team vest is great too, it's non-CGA, but keeps my head above the water just fine..
