Vizio 47" LCD 1080p from Sams. It has 4 HDMI ports and a VGA connection for PC input. Picture is great and it has the new QAM tuner (QAM-based HD programming of local stations is sometimes available to analog cable subscribers, without paying the additional fees for a digital cable box. The availability of QAM HD programming is rarely described or publicized in cable company product literature.)
I get several digital channels and some HiDef on ABC/CBS/NBC stations from Comcast without digital cable. Great price compared to Sony (plus 1" larger<a nit>, and more HDMI ports ) and close in Picture quality after watching the in store TV for more time then I want to admit to. Sound seems good also and remote is nice. We think its a good size for a ranch.
Go as large as you can go/"or want to spend" because with the Hidef aspect ratio of 16x9 and better picture vs 4x3 for previous TVs that were 36" (diagonal) before are now "sized at about 42" with the extra space on the sides and you either have to make the picture wide/panoramic or zoom to fill in the screen a lot of the time.
