If you're not interested in HDTV, buy 4:3 if you want to buy something that can be ready for HD, absolutely buy 16:9. By definition HDTV IS 16:9. I've had a 16:9 projector for the last year and I really prefer the 16:9 format over 4.3, even for regular TV viewing. The first few times, I was bothered by the stretched mode, but now I don't even notice a difference.

I probably will never buy another 4:3 set again.
