I have a Cal comp 20 x 24 drawing board 3 with 4 button mouse, cables and usb to serial adaptor. I have tested it, works great and looks like it was never used. comes with all original accessories and documentation. I see its amazing power and precision, but I just don't use/need it.
you will have to figure out the drivers for your specific computer. only took me about an hour and I'm not all that savvy.
how about $100 + shipping. OBO
