OK, you guys got me with all this new laser projector talk. I'm going to be getting my B stock projector on Friday or the following Monday. I couldn't quite swing for the 4100, but I'm sure the 3100 will still be a worthy upgrade from my previous RS-420.This will be my third JVC projector I've gotten from AV Science, and I've been happy with each experience. This one should be no exception.Scott
