Sniping tools are a good way to make sure you win eBay auctions. Basically, you set up your sniping tool by pointing it at an auction on eBay, letting it now how much you are willing to pay, and it automatically does the bidding for you. But unlike the automatic bidding already available in eBay, sniping tools are designed to swoop in at the last second to make sure your bid is the final bid.

JBidwatcher is one such tool. It's free and it runs on Linux/Mac/PC so just about everyone can use it. It also has some cool functionality that other sniping tools don't. It allows you to set up to bid on multiple auctions of the same item (if more than one is up for sale) and it'll try to get you the lowest price. As soon as you win one of the auctions, it stops bidding on the other items.

It's really easy to use, and it's free. So if you are tired of losing eBay auctions to other bidders at the last minute, you might want to give a sniping tool a try. By the way, this is "legal" on eBay, they do not prohibit or ban the use of these types of tools.
