who ever told you LCD digital monitors are crap is talking thro his/her hat.
I have used a 17in TFT for years and do some photo work not a problem the normal key is the graphic card you use. I can advise you go for a 19in plenty of offers eg dabs ebuyer etc shop around and you will find one at a price that suits you. TFT have come on a lot from only few years ago
the main comparison TFT with CRT is the simple fact weight Tft is a lot lighter and does not take up space on your desk
Yes the one I have a Relysis does have 1 dead spot on the screen but nowadays you wil be lucky to find any manufacturing has progressed because of customer returns in a few instances
My advice GOFORIT
