avsforums is the place to go for information. there are more experts there than anywhere else. Keep in mind with a DLP tv vs. an LCD or Plasma is your viewing angle will be significantly reduced. If you hope to view the tv from above or below or extreme angles from side to side, stay away from any kind of DLP tv.
As far as projectors go, there are some unbelievably bright projectors but you are going to have to spend 300+ for the screen and about 1500 to get a decent HD projector. You will still have issues with natural light washing out the picture.
