I don't think either version looks any good, frankly. You say the new one is "a jump back at least 10 years in web design." Well the old one looks like it's 15 years. Besides, it looks like a cross between Craigslist and ebay.

The worst part about the new site, from what I've seen, is that when I looked at the sale listings, and hovered over the small images attached to each one, a larger version would come up, but it would come up about 200 pixels down the page, covering another listing and looking really unprofessional.

Anyway, I've never even heard of the site, I think I'd rather post my stuff on Craigslist where it'll get some eyeballs.
