I think eBay has it's own form of escrow, you might want to use their's if you are going to do your online auctions on eBay... I'm not too sure about the specifics of it though, but it's always better to use the escrow that is provided by the aucioning group rather than from a different group. I believe that that NATER is right w/ tradenable... they are the ones doing it for eBay too, so they might be a very reputable company for you to look into. Good luck =)
