Wow what a thread, my unemployed arse took forever to read it but it was amusing and informative!
I was able to try numerous set-ups and my share of rentals before laying cash down. Renting/borrowing has it's drawbacks, more notably -constant buoyancy changes.
My list:
jacket BC -history, now BP/W
Console computer -now wrist mount
Old AL80, got the shanghai when I didn't know better
SS1 -came with a used equipment purchase and actually had to use it once, then replaced by regular secondary reg. Flows great but too cumbersome.
I've been lucky with my eBay purchases, perhaps because I really check things out. Buyer beware!!

I have to agree on hyper-stretch wetsuit materials, mine looks like a Lamprey grabbed me. I now use Velcro loop tabs to cover the Velcro hooks on the suit until I put it on. This is a PITA and the suit manufacturers could easily add tabs for this purpose, kind of like the ones some gloves have.
Titanium linings are great, you just need a dive skin to slide into them (and skin hides all the scars from my recent health issues, I'm looking forward to diving again)
