Most of online auctions are based on the prospect that a number of folks will bid early and get caught up in the frenzy as they invest themselves in the auction process.
Sniping tools like isnipeit do take a lot of the emotion and adrenelin (fun?) and turns it into a "what's the most I would pay for that" equation where you're inclined to make more rational decisions.
