I have recently decided to buy a rear projection tv, with the help of this fine forum. However, no sooner do I make this decision than my friend begins to suggest my money might be better invested in a video projector. I know little about projection televisions, but next to nothing about video projectors. The little bit of research I have done tells me they are very expensive. What I want to know is what is the absolute least amount of money I can spend on one of these things without sacrificing any basic functionality and quality. For example, I would like to be able to watch TV and play dvds in a reasonable amount of light (as if I were watching a tv) and little else. How much would I have to spend to be able to do this?
