I just found this site called Fat Fingers which helps you find eBay bargains. Basically you type in what you want and it searches eBay for typos. Therefore the items you want come up with few if any bids because people can't easily find them by searching normally in eBay.
I searched for printer and it tried a whole host of typos and found loads of items with no bids. I hope this helps someone find a bargain or two!!
