We bought four of these (new) for our office. Only three were used so we're selling one unused GTCO Ultima II, 12x12 Graphics Tablet (Digitizer). We paid $450 per unit. Comes with a wired 16-button puck. The tablet is designed for graphic arts, CAD, GIS, engineering, and apparel applications. Both USB and RS-232 serial connections to your computing hardware. We're using them with AutoCad on windows-10, but you'll have to do you're own research on your application.
