Prospector Lite is an advanced search tool and auction sniper for eBay, that makes it easy to track and find bargains that you are interested in. You can create detailed search queries, using keywords, exclusions, and other filters, even with support fro regular expressions. The searches can be saved and organized into custom categories, so that you can easily refer to them later, using the latest eBay results. Prospector Lite also offers server based sniping services that enable you to place last minute bids, even if your computer is not turned on. The Lite version is limited to 30 searches a day, and 15 snipes a month, which should be plenty for most users. If you need more searches, you can upgrade to the Pro version.
