D, I read through your post (#47) three times now and you're going to have to help me out here. I totally understand your bidding style. I have used it myself with success. In real auctions. Face to face. I bid from the get-go (well, when the auctioneer comes down to a realistic price) and I bid fast. If it seems the other person wants it, and I still have room, I'll jump the bid increments higher to get them out.
But I have found the opposite effect to happen on Ebay. I've done it myself. I see something I think I need. I bid, but a previous bid was higher. So I sit there looking at the new high bid price, thinking 'how much higher is it?' Then I bid again, just to see if I can beat it. When, originally, I had set my price with my first bid.
Bidding my max that I'm comfortable spending at the last second doesn't give someone else the luxury of sniffing at my bid.
Of course, it's all moot when the auction ends when I'm not at home.
