I agree totally with Joe. Place your max bid and walk away or at the very most, watch. You may get it and you may not. But, you won't suffer a nervous breakdown and you won't be enticed into a bidding war. I often see people who say someone came in at the last second, just a dollar more and beat me. That may or may not be true. They may have had a higher max bid already in there and only needed to beat you by a dollar to win. I'm guessing that happens more often than not.
