I have used Auction Sentry for over three years. I love it mostly for its ease of use and reliability. In a nutshell, you can add an auction with a mouseclick, add notes to each item on the list, and are notified of any bid change instantly.
I let Auction Sentry run in the background, and enter my high bid days before auction end, so I don't have to remember when it ends, or even be at home. I set my snipe time to 2 seconds before auction end, and that's exactly when my bid is placed (if you're on dial-up you should probably give it more time to go through).
I have won many auctions using Auction Sentry, and I consider it a wise "investment". The program is updated constantly to keep up with eBay changes. Dan, the creator, will answer your questions immediately and in a friendly manner. You just can't go wrong with Auction Sentry.
