if you have the room or even a seperate room look at crt projectors.i got one and am almost finished fitting out the upstairs of my garage.friends and relitives have been getting demos over the last few days and seem well impressed.90" screen and am going to go bigger.
the experts tell us that nothing matchs crt for quaility yet and defo not on picture size.
