I bought one of these about two and half years ago, and at the time of purchase this was the cheapest 22" TFT I could find at £135.
Was it worth it? Yes and no. It's been well-used so far and as far as a screen goes it does the job - there's no dead pixels, no visible ghosting and the colours are fine.
However, the screen's backlight has always been a bit 'cloudy'. Ofcourse this backlight bleed is only noticeable whilst viewing dark films, moreso in poor light. The fix is boosting the brightness and colour vibrancy software side (ie. ATi's control center) - increasing the monitor's brightness just increases the backlight bleed visibility.
Whilst I expect the amount of backlight bleed probably varies from panel to panel with this model I'd say there's a good chance of there being some backlight bleed if you buy one of these. If you're just doing work or normal computer stuff you won't even notice it. If you're planning to watch movies and play games - I'd give this one a miss.
Design-wise it's black and relatively sleek. The screen tilts back and forth smoothly and has VESA mounting points. The OSD controls are under the screen (menu, auto, left, right, power). The OSD has everything you'd expect, though the on-screen border of the OSD is a bit weird, since parts of it are missing.
The back has a VGA port, a DVI-D port, and a 3.5mm audio-in jack. The DVI-D port is HDCP compliant and works with a PS3 using an adapter - however - the monitor is NOT 16:9, but 16:10 - so the image is slightly stretched. For this reason I don't recommend using this as a TV or for something that won't support 16:10 resolutions.
You get all the usual crap you'd expect in the box. A useless CD-ROM that you'll probably never touch (containing the manual), a VGA cable (good job I had a spare DVI cable), a quick start guide and an audio cable (if you're mental enough to use crumby TFT speakers).
The panel comes with a three year warranty, I have no experience of their warranty service, but the policy is "3 bright sub-pixels, 4 dark sub-pixels, or a combination of 5, and no more than 2 adjacent defective pixels are allowed in the viewable screen area".
I think that pretty much covers everything. It's worth mentioning that the screen sometimes doesn't detect signal when it's initially turned on. The fix is to... turn it on and off again ;)... or you can disconnect/reconnect the cable.
