Retail marketplace- is there any good one you recommend?

or.. should I just build one?

[flex55]

I'm looking for a software that can faciliate a marketplace on my site- including credit card processing, upload for merchants, etc.
does anyone know something good, and, not *very* expensive (free is the best, of course)?

my other option is to sit down and develop it, but i'd really rather not to.

tnx.

I always thought Zoovy was kinda cool ... I think its around $50 a month. Zoovy can also launch eBay auctions right from your control panel too with a couple of clicks which can help you reach a lot more people without having to "manage" auctions.
