Why just restrict the search to buy-now items? In my experience more of the esoteric stuff seems to go on straight auctions and buy-now is used mainly by commerical retailers.
Yes, I plan to support things other than buy-now. This was just the simplest way to get something running.
My plan is to have it wake up every hour, check if it's won something in the last 24h, and if not then do a search for items to bid on that are closing in the next hour.
