I won a auction lot, then why do I feel like a loser?

After to going through all the lots in the latest Comiclink auction I had picked out all the Thrilling Comics lots to bid on. I was going to win one of those lots if it was the last thing I did. It's been a long time since I had added a comic to my set on the Registry and here was a good chance to do that. My main goal was to get either the #43 or #71 as they were the highest grade of the lots. Things started going bad as soon as the first Thrilling Comics lot sold. It went about $30 higher than I was thinking. After a couple more, that went higher than I was willing to pay, I knew I'd have to put a pretty good bid in to win the #43 issue. I had set my limit in the mid $200 range but now knew that won't do it. Okay, so it was, kill the budget time. I put a bid of a bit over $300 on the lot with about a min. to the end. I was halfway hoping to get out-bid as it seemed way to high to pay for a mid-grade Thrilling Comics. In fact, I was hoping to get outbid when there were a few seconds remaining. , I won the lot. I'm now the proud owner of a #43 Thrilling Comics that I feel I overpaid for. I'm happy I get to add something to my Thrilling Comics Registry set after a long dry spell. I'm happy to have seen so many Thrilling Comics come on the market, as I rarly see more than one or two a year that I can actully afford. But still, somehow, I feel as if I was a loser instead of a winner at this auction. Oh, and here's the bad news. I still have about 10 other comics I know I'm going to want to overbid on in the next few sections of the auction. Wish me luck or beter yet, don't.
