I got totally boned out of an ST-V board on ebay last week. It was listed as "Die Hard Game", and was bidding at 15 bucks, though it was clearly an ST-V with Die Hard Arcade in the pics..
So I was waiting to snipe it, woud have gone up to 75 (and easily got it). 45 seconds left, my PC froze up, for the first time in 6 months, the POS froze up right when I needed it. I sprinted to my wife's office and tried to log in in time, but to no avail.. Some ass got to walk off with my ST-V board + cart for 15.50 + shipping!
Bah. If that was you, just know that the laws of karma will one day allow me to screw you out of a great deal.
On topic, 50-75 ish is as high as I'd go for the mobo, games could be anywhere from 10 bucks (die hard) to 150 (radiant silvergun)
