The first two seemed very promising, webstore.com and ebid.
I looked at webstore.com first and it sounds just what I would like to use. The main disadvantage with this is that there are ads on the site, however this pays for the auctions and so there are no fees.
The second site is ebid. I was able to find a UK version of this site and I am aware that there are other ebid sites covering most of the world. The main advantage of this site are the fees, which are lower than those of eBay.
