I have the H610P. It's really nice (no tilt, though), probably not as nice as a wacom but it was fairly cheap. Don't know about newer ones but with mine there was an issue with drivers, I think you had to install the ones from their website before attaching anything or it didn't work or something like that. Definitely not use the ones on the included CD (as if anyone has a CD drive anymore anyway...)
Haven't used mine in 2 years ( :$ ) but plugged it in today and it works! Installed drivers from huion site and was good to go.
Not sure if a tablet is any good for cad, but will have a proper play tomorrow (NJ) and see if I can set up the buttons in a sensible fashion to make it usable.
What sort of 3D? I can see it being ace for direct modelling like Blender etc., but CAD is very keyboard/number driven. Organic shapes are much less common.
Drill Your Own Hole, the first album by the awesome Gaye Bykers on Acid. In some lists as the best album gimmick ever, the first thousand pressings allegedly didn't have a hole in the centre. It wasn't exactly true - they just didn't have holes in the label. That there is an ultra-rare 'undrilled' copy.

Part of me is wondering how beneficial I'll find it - I'm probably comfortable enough with a mouse to not see accuracy benefits, but being able to vary pressure should be useful enough that I use it for layer masks at least every other month. :)
Plus it'll allow me to dabble with drawing/painting, without worrying about having/wasting physical materials. Hopefully that lasts beyond the first fortnight...
