If you are interested in a projector, then why not tell us about what you are trying to achieve. This really isn't the right thread to discuss it in though. Start a new thread, tell us about your space, what you are hoping for, etc. DVD is a pretty weak way to show videos at 100"+ diagonal. Blu-ray Disc is a great starting point for movie viewing. It goes downhill from there.
Best entry level models: BenQ HT2050 & Epson HC2040. Both are under $1,000 and do very well for the money.
