In addition to my 20D, Ikelite housing, ports, port bodies, pelican case, I have a Canon A80 and its Canon housing that I'm looking to sell.
I don't expect Wetpixelers will be looking for this 4 MP P&S from 2004, but perhaps someone's spouse, significant other, or kid might like it.
I got decent photos with this set-up. Examples here.
Paid over $500 for this kit back in January of '04. The first $220 takes it. I can pack everything in the housing box. You'll need to buy new AA lithium ion batteries. I'll include a 512MB CF card, which is pretty adequate for this camera.
