Check them out for yourself, but the new true flat screens give a sharp picture.
But I think they are more expensive.
Ultimately it depends on your input source... if you have a s-video input from satellite or digital cable,or component video from DVD's then you may want to spend the extra cash.
But the newer conventional tv's from Hitachi, Panasonic and Toshiba give you all these features and a pretty dam good picture, for less money.
I personally have a 32" Hitachi Ultravison which has a fantastic picture, all the features I wanted and good reliabilty (check Consumers Reports)
Get a 27" at least
You have lot's to choose from... Good luck!
