Does anyone out there have this setup? I'd like to get a better television but I don't plan on upgrading my service to HD any time soon. (I'm addicted to my DTivo but not willing to shell out all the $$ for an HDTivo.) Just taking into account the SD and not DVDs, is it worth it to upgrade the TV? I realize that you'll get pixelation with the larger screens. I'm still not sure how large I want to go yet with the tv. Thanks.
