There are few aspects to consider before deciding on a projector, because you cannot return the screen easily and some form of installation is needed. You can get a reasonable throw at 12 feet distance but bear in mind that the AV equipment is at the front, so there will be an HDMI cable going across the room (unless you want to get a wireless kit which may not be reliable). It is really difficult to recommend you a projector, considering the number of times you change your mind. When you come to a stage where your mind is stable and you're looking for a long term investment of at least 3 years, then you can think of a projector which has the potential to reward you with a far superior viewing experience as long as the lighting conditions are right and the screen is right.
