AuctionCut

Try these guys out, its brand new eBay software that lets you generate multiple sku's type eBay listings within an actual eBay listing called eBay configurator.

You can go to their site and fill out a request for a demo, I have seen numerous auctions popping up with these at early stages, they are all are making money based on. If you're not a powerseller, this allows you to save TONS of money to become a powerseller and not have to pay for having hundreds of auctions up, but rather having one auction to sell all your products. Then the customer is able to generate the item he wants uniquely for himself, and an auction is created specificly for him so instead of having to post hundreds of auctions to sell just one, create ONE auction to sell all your items!!
