In my last job I had an 454 on loan for use at home(since the co had switched over to TFT's).
I was very impressed with it in most respects in comparison to the 15'TFT I use at home, so long as you take a little time to set it up correctly (I used the demo version of Display Mate and a CRT setup utility made by Nokia).
Text output is not as sharp as a TFT but in all other respects the screen image was more vibrant and seemed less 'flat' (if that makes any sense to you).
It will also comfortably display 1600x1200 (at which there was almost no moire interference) though if working at this resolution a lot you really need to be thinking about using a larger monitor.
I was all up for buying one but now feel that I would prefer to spend my cash on a 19' TFT since my day to day needs are more text and number based and in that regard a TFT suits me better.
