Hey I had originally suggested the Panasonic ST60, but the S60 is also a good choice. Any LG Samsung Panasonic full 1080p plasma will be fine for gaming in a basement. Make sure its not a model that claims 1080p but only refreshes say 900 lines in motion. Don't rush to buy a TV now, wait until Jan-April when they announce new models and clearance the old ones. You'll have your pick at many great models.
edit: Plasmas are not just to be hidden in basements, but you don't have to shop for one with glare reduction if that's where it will be.
