I use Auction Sniper 6 months. Excellent sniping tool! Not only it allows you to bid in a few last seconds, but also you can bid as a group in order to increase your chances to win the desirable item. Their server(s) is located close to eBay servers, and it's a significant factor - if you want to outbid the competitor. Some other services at this program is great - they warn you before the end of the auction if you were outbid - bidder has some time to evaluate the information. I live close to US border, and all my friends from Canada and US use this software. Great tool!
