Glad the scam was averted, but some general thoughts on projectors. There is NO better way to watch a game, movie or HD TV than on an HD projector.
My main TV is a 720p Infocus projector on a 118" Carada screen. It was a $3k projector when I got it, but that was probably four or five years ago.
As to light, if you have a fairly bright projector, you don't need a completely dark room in terms of inside lights, but you do need to be able to eliminate nearly all sunlight, because the sun has a **** load of lumens.
Watching Alphas on it as I type this with a ceiling fan light on and a table lamp on next to my wife's side of the couch.
Biggest downside of it being the main TV is that I replace the bulb every 13 to 15 months.
