iSkn Slate 2+

Perfect addition for any tablet/computer. You simply plug it in via the usb cord and whatever you draw on the paper, instantly draws on your screen, great way to upload your work for artists or people who like to edit their work through illustrator, etc. Has only been used once since i got a surface pro. Sells for $200 online, plus the $20 for the "Pen" stylus so you don't have to actually draw on paper if you choose not to. Selling for $150 but open to reasonable offers.
