I've used ISnipeit before too, and it works pretty well. NOt free, but 30 day full eval is, and I just reinstall, clean registry, and start over.
FYI for the ppl that just said to bid:
anyone that says sniping doesn't work doesn't understand frenzied bidding. If you bid on an auction, if your high bid is higher hten the current price, the auction price goes up, and the other person has a chance to match it....and the stakes get raised.....and so on it goes.
If you snipe it, you catch it at the last possible moment, and if your price is hihger then the auction's max price, then you do win, but you win at a minimal cost.
BTW...thx nFs4 for the link. much better then what i was using.
