I only occasionally use Ebay for competitive bidding items, but when I do, Gixen is my friend. The service is remarkably well designed, and while I might be outbid once in a while, Gixen gives me a highly flexible mechanism for sniping. It not only allows me to relax and let the automatic process work, I think it's likely I save 15 or 20 percent on average. I recommend Gixen highly.
