Carl,
If I could just offer you a suggestion on eBay since I see you are just starting out in it. It doesn't work like a normal in-person auction. If you bid just the starting amount, in this case, $120, someone could come along and just a few seconds before the end of the auction, and enter a bid above yours, say $122.50 ($2.50 is the minimum bid in this auction) you are out of luck. He wins as there is no time for you to react. This is very, very common on eBay. Your best strategy is to think about how badly you want the item, bid that amount, wait for the auction to be over, if you win - great, if someone "snipes" your auction at the end and wins, well that's the biz; there should be no regrets on your part, the model ended up costing more than you wanted to pay. I hope you get the model though!
Any questions, ask; I have been playing this game since 1999!
