Every rear projection TV ive ever seen hasnt had the nice contrast and colour balance of a CRT, and only look useable if you sit 40 foot away from them. Also - theyre rediculously big, and do they need bulb changes too? NOT sure - but if they do ill bet their not cheap.
I'd never buy one to be honest.
Either get a cheap plasma, or a big CRT. Front Projectors are excellent for movies, but useless for watching day to day TV, you'd want to use a projector as rarely as possible to make the £250 bulb last a long time.
