I bought an EX 200 as part of a package shortly after my Open Water certification about 18 months ago. I've enjoyed it, and it was clearly a good step up from the rental rigs I was using then and the ones I used a Bahamas trip recently.
I am a newbie, so weigh my experience accordingly. The biggest thing I like is the two zipper pockets on the sides. They hold a bunch of stuff, and I do not have to have tons hanging off me. I have two mild complaints: First, I don't like the "D" rings on the shoulder strap. They are plastic and are not just open rings. They have a pattern which creates several separate spaces to clip into. I find them too small for easy use. Finally, I think the inflator hose retainer is a bit too low, so that when I pull up to deflate the BCD on ascent, it has more of a bend than I would like. I just have to watch it.
Overall, I am pleased with the purchase and plan to keep diving mine for as long as it works or until I gain enough experience to figure out something better suited to my own diving style.
Good luck.
