I should say that I have seen some high end LCD's and they would be the only thing I would buy and I find them enlivenment to my cheaper crt in visual quality. With the expection of the ones with the glass looking stuff. They just look sharper and I really like it!
I would only replace my $500 crt with a $900 LCD and my big $1500 crt with a $5000 crt that does not yet exist...
