I, too, use esnipe and love it.

The best feature, for me, is that as Taffy mentioned, you can withdraw a snipe bid before the end of an auction, if you no longer want the item. This is really handy when you are watching multiple auctions for the same item. You can't bid on all of them on ebay at the same time without risking ending up with multiples, but you can set esnipe up to where you can bid on them until you win one, and then it cancels the rest.
