I've installed a bot that scans eBay auctions on an hourly basis and posts its findings in this thread.  The bot is attempting to find class 3 rares, but will occasionally turn up something unrelated or not rare -- most likely due to keyword spamming on the part of the seller.  If clutter persists, I'll attempt to adjust the innards in order to filter it out.

Enjoy, and hopefully Auction Hunter finds something you missed!

Foul

P.S.  If you notice a poorly-rated seller's items showing up here, please let me know so I can filter them out.
