I have most of the hardware for my near future HTPC finalized and at the moment my 27 inch Wega will be the centerpiece but I would like to try a projector to see if I like it. This will be for an apartment with a fairly large living area considering it's a one bedroom (tv is 7 feet from couch, chair) but I don't need a huge screen. I know next to nothing about projectors but I would like to try one for a large white wall and see if it's something I could live with. Any suggestions for low cost, fairly good quality projection units?
