I have a Samsung 40" LCD and its fantastic. BTW, samsung manufatures the panels for other big name big dollar brands (see sony).
My tv has a 5000:1 contrast ratio and is pretty nice..
is 720 the max display? if so, it'll downscale a 1080i image to 720 - not getting full image quality.
Only reason I picked up the lcd is becuase with 1080p coming out you'll be left behind the curve.
JMHO though.
