I'm so glad I didn't opt for a cheaper version (of which they're are many around). I bought this on the strength of seeing it in store as I'm interesting in hand-drawn animation, and wanted to have a pop at it myself. Aside from this, I know it'll have many other applications as I have experience in graphic arts, and after attempting some tracing it does the job superbly. Theirs also a nice little area to house your pencils/tools so they're not left on your desk.
I do have a few quibbles, though they're more personal matters. I've found the 'hum' noise coming from the bulb (an energy saving one) a little monotonous at times, specially if I'm concentrating hard. I'm quite aware of sound, but perhaps others may not notice it as much - I sometimes just stick iTunes on my computer for some light background music.
With regards to the light, it's a very nice output but does not stretch to it's full brightness across the whole of the workspace, because the bulb is at the top. Whether this is a problem depends on your application, of course.
The only other thing, as mentioned before, is that the bevel/groove which holds any background paper in place is a bit too tight, even too slim to fit two pieces of paper under. I would have like to have seen some removable pegs on the top or bottom to keep things in place better.
For the price however, this is essentially a very good unit that only suffers from some logical flaws. With it's grooved under-side for ease of carrying, energy efficient bulb, and large spread, this is a whole deal better than the cheap knock-offs at half the price.
