hm, well as ive just "impulse bought" a 2005FP.. im not one to talk about being careful. lol
i was originally in your situation, wanting a really nice 17" tft to ensure i wasnt dissapointed due to dead pixels, low quality /motion blur, slow response etc... but after a few weeks considering everything, spoke to lots of people, everyone that has a 19" is happy they bought that over the 17" (can add to the price alot to get a nice low response .. some nice hyundai imagequests avail, aswell as samsungs (and dells who use sammy panels). i was gona get a top of the line iiyama 17", then i saw the top of the line 19" and allowed myself the extra £80 for it, as i figured monitors are gona be standardly 19" and above in a few years, which i hope it would last.. ive had this crt for 7 years now, and i thought, why not.. looked around, asked more people, "GET THAT DELL" was the impression i got.. aria.co.uk special offer saves you £129 on a 2005FP (only £350 inc vat).. so what the hell, 4 inputs for uni (tv / dvi for comp / camera svid), 12ms response (for a 20.1" widescreen tft.. nice. ), good contrast and brightness. ill let you know on my opinion when i recieve it, it best be right as i spent most my money on it
general message from everyone suggests bigger = better, but dont go low quality in exchange for larger screen. dells are very good price and qual atm, and as an ex-avid CRT user ill let you know how it compares in fast paced games, tv / dvds, desktop, appearance etc
