Okay so My buddy is building a man cave and asked me to help with tv selection..I told him since he is in a basement and wants the most for his money why not get a projector and screen, he wants to stay at around 900 for everything (screen projector and mounts) can this be done and do you have any you guys recommend, also how long are projectors really good for and whats the long term cost vs lets say a rear projection.
