If you bid your true max, you would have won, wouldn't you, whether your sniped or not? Sniping programs are for people intelligent enough not to be trapped into the psychology of an auction, raising their max higher and higher than it would have been. I hate when two idiots get into a bidding war ahead of time. Here are the two sniping services I've used:
www.auctionsniper.com
www.bidnapper.com
There are a few more. I'm a heavy bidder so I use bidnapper (which is pay-per-a-period-of-time) but auctionsniper is pay-per-snipe, which might be better for lower volume bidders. I hope more people use these, which should ultimately keep prices DOWN on records, which are ridiculously high already. Wish people would bid intelligently and I didn't have to use the program.
