I have a guy on Craigslist offering a recently purchased (with transferable warranty) KDL-40S5100 for $450. Considering the cheapest used on Amazon seems to be 700+, I was thinking of biting, but even though the reviews for the TV are generally positive, I wanted to see if anyone has any first hand experience with this as a gaming TV, as that's going to be my primary use. I want to make the offer as soon as I can, so any reply within, say, 12 hours would be awesome. I know it's a long shot, but for nearly $500 bucks, I figured I'd try. Thanks!
