There are two other options- RP LCD, which isn't quite as bright or offer quite as wide a viewing angle, and LCoS (Liquid Crystal on Silicon) which is supposed to be cheaper and at least equal to DLP in quality.
actually most people who come in find the lcd "easier" to watch, and LCoS is interesting to watch, its really more like watching something in 3d, once you get used to it the pic is great
