I have been an eBay-er for years (over 15). Over this time I have used several "snipe" services, but Gixen is really the best. Even their free service outperforms many of the other much more expensive services, and their pay service is unparalleled. I have sniped literally hundreds of auctions, many at 1/2 or less the value I would have peid if bidding head to head with others. I highly recommend their service.
