Projector VS some other type of HDTV

Looking to replace an older CRT HDTV with either a projector or some other type of HDTV. This is going into a former 2 1/2 car garage that has been converted into a home theater room.

Apart from the fact a projector gives a much bigger picture, is there any reason to purchase one over LCD or plasma HDTV?

The 'knock' on projectors is that they don't provide the crisp type of picture one can get with a LCD or Plasma HDTV, any thoughts or comments will be appreciated.

Thank You
