I came across one of these at a "Bargain Hunt" store. The store is an Amazon closeout/returns/overstock brick and mortar chain that clears out all kinds of things from Amazon (and some other places too). I was able to get one that's brand new for under $200. I have been playing around with it for a couple of days and, for the price, it's not bad. I don't think I would pay more than I did for it though.
I also own a Cintiq Companion Hybrid and used to own a Cintiq 21UX and had I not been used to them, I might like it more, but there is a pretty distinct difference. The parallax is a little greater with no way of adjusting it (no placement calibration tool) than Wacom Cintiqs and even with the 2048 levels of sensitivity, it's a little more erratic. Responsiveness varies from program to program. I've tried it in Photoshop, Sketchbook and Illustrator and it seems like, consistently, starting a stroke is pretty jittery and just doesn't feel as graceful as working on a Cintiq.
The TFT display is bright and clear but it's hard to dial in to get really nice color and the shallow viewing angle does cause some pretty radical shifts. You have to be directly in front of it to work on it. Trying to get it to match my Macbook screen, even though they are the same resolution, is really tedious. I do like the construction of it as a whole. Super light weight and the stand works GREAT (MUCH better than the stand that comes with the Cintiq Companions!).
I was REALLY hoping it would be better than it has turned out. I guess, since I do have a Cintiq already, the difference is just a little too sharp. I was kind of hoping to be blown away by it or at least impressed with it enough to maybe sell my Companion Hybrid since I'm kind of ticked at Wacom for not supporting it any better than they have. Not the case though
Had I never used a Pen Display before, this WOULD be a good, low cost introduction to them. It is good enough for someone to get the idea of whether they like the idea of drawing on the screen or not. If you don't have the funds for a Cintiq but want something to get started with, it's good for that. An IPS display would go a long way towards fixing it and a better set of drivers that offered position calibration would be GREAT!
