I am looking to set up my first projector for my apartment, please bare my ignorance. I understand that it also depends on my room, but I'm not looking to set up anything too complicated. I want something that displays as clear as an HDTV. Is there a cheaper alternative than the 5020ube? I have read numerous other threads, and seen people using projectors that cost way less. The photos of the display looks clear, but course I can't tell without seeing it live. Please help, thank you!
