You will never get as good of a picture with a projection TV. Just won't happen.
LCDs (and LEDs) are the trend for the future but dollar for dollar, the best buys are still plasma.
A brother I know just bought a 60" LG plasma and it is impressive (about $1,600).
IMO, LCDs still have the refresh rates that are too slow to watch fast-moving sports. It gets blurry when the camera moves quickly.
But, as mentioned above, if you plan on using it for gaming, LCD is the better way to go.
