Complete noob with Home cinema projectors etc.. but I have a lot of experience with standard one's. My two concerns would be a, the bulb which you highlighted, they can be very expensive and b, the noise they make. Obviously they get very hot and only have room for small fans so they can make an awful racket in low ambient noise situations i.e. home cinemas..
Could be wrong of course since a lot of people do this but it's worth noting when asking for info on them
