good guide / reviews for buying a TV

[lesch2k]

are there good sites that review 27 and 32 inch analog televisions - i couldt really find any.

for instance how much better is a 2 line or 3 line digital comb filter in terms of picture quality?

if you have the space would i be better off wiht a 27" flat screen or a 32" TV, both run around $300-$350.

and how much better is component input from a dvd player vs. svideo vs. the red/white/yellow ones?

thanks
