I am looking into purchasing a DPV. I am 230 lb and will use it for wet and dry suit diving, mostly great lakes. I am not opposed to spending money but want to get the best value for the first one, I have two boys who are now diving, and I need to equip them and the get additional ones. The first one if not the cadillac would be passed down and then I could get a more expensive one for myself later if that is necessary. initial $500-1100 range, suggestions?
