Chances of me buying a BPW used is slim to none. I don't want ragged out wings or bladders. I don't want ragged out harnesses.
This made me smile. I bought my singles rig used, from NW Grateful Diver (which means WELL used) five years and probably 600 dives ago. I replaced the harness shortly after I got it, not because it was worn out, but because I prefer other webbing. That harness is still on the rig! The cordura cover on the wing is a little fuzzy, I admit, but otherwise the gear has performed without flaw for five years. That poor little plate and wing probably have close to a thousand dives on them now . . .
I think the only "experienced" diver I know who seems to buy everything new is Bob. But then, he turns over his used stuff to help defray the costs of the current toy acquisition
