How is it like to play games on a video beam?

I've played wii on a projector, and it is a HUGE pain in the ass.  we had a gamer day in the anime club I attend, and the sensor bar was a pain almost the entire time.  as stated above the picture also looks inferior to a TV.  How much are you willing to spend on the projector?, that would make a huge difference.
