Fight fire with fire and snipe yourself. It isn't unfair, just smart.
Actually, snipers or at a slight disadvantage because if 2 bids on an item are the same, or there isn't enough difference between them to meet the minimum bid increment, the 1st bid in wins.
(Automated) sniping is a convenience for people who want to avoid drawing early attention, inexperienced, ignorant, "nibbling", and/or emotional bidders, and bidding wars to an item that early bidding may bring.
http://www.hidbid.com is a good service to use if you don't have the time to do it manually.
A couple more benefits of sniping:
1. Sniping is actually a way of combating shill bidding - when the seller or his buddy bids on the item until they're the high bid, and know your max, then retract their bid, and use yet another account to bid on the item, bidding just below your max. You don't give the shiller time to retract their bid in order to leave you as the high bidder, close to your max. You can't do much about a shill bidder letting their bid ride to the end of the auction, if it just raises but doesn't exceed yours.
Also, look out for 2nd chance offers, as they would be a reason for the shiller to let their shill bid ride, you may want to decline any and look for a different seller with the same item. Unless of course, the price seems ok with you, even though possibly artificially jacked up.
2. You can just cancel a snipe with maybe 5 minutes (I guess it depends on what service or software you use) before the end of an auction, if you change your mind about bidding on an item, and your bid won't be placed. If you place a bid on ebay and then retract it (not a seller's or ebay's favorite thing), you can be blocked from bidding on other auctions after doing this a few times, not sure what that # is.
Anyone bidding on ebay should understand ebay's proxy bidding system, and have an idea about their bid increments:
