I recently purchased a Sharp LC52E77UN and gotta tell you, the TV looks pretty darn awesome. Firstly I would recommend the 52" size to anyone if you have the space. Now onto the picture quality - I was a bit disappointed w/ the quality of some of the SD channels (abc, fox, etc..), however others like food and discovery channel were definitey above par - I blame it on the DirectTV subscription I get in this condo building. I am waiting to get my Mini-DVI to HDMI cable I ordered from amazon to see the difference in quality/sharpness of true 1080p when I hook my mac in. I checked out the HD version of the TV's older models in best buy and it just looks plain awesome. Not sure if I am going to subscribe to HD for now as I don't watch that much regular TV to pay $260/yr. Instead, I have been debating on getting roku (for netflix instant watch + amazon VOD) for $120 shipped w/ cables and a home theater system which would probably cost me together the same amount as HD subscription for a year -- I probably have to wait for labor day sale or something though.

I'll post pictures and more details about the TV in the upcoming weeks as I get to play around with it more.

Got my Mini-DVI to HDMI cable few days ago. The macbook to TV hookup is awesome and the picture is phenomenal - crisp and clear. I also followed the calibration settings found at avsforum and a bit of my personal tweaking and the video quality increased drastically for both SD channels and regular DVD's
