JBidwatcher is a powerful eBay-user tool implemented in Java. Its features include tracking of auctions, bidding, sniping (automated bidding in the last moments of an auction), and a unique multisniping feature that allows you to snipe on a group of auctions, but stop the sniping as soon as you win one. It also includes remote Web-based management, XML-formatted save files, drag and drop support, some support for auction sellers, and dozens of other useful auction features.
