I use a JVC idla rs2 for projecting my Bluray films . It is one of the best sub 5000.00 image I have seen. The screen is very important but to keep within my budget and within my high expectations, I use the GOO system. You literally paint your screen, to the desired size for a price that is well below the competition i.e. Stewart and Drapier.
I Highly recommend it !www.gooscreen.com/systems
