I was looking for a while until I found one just for shipping ($ 8) . Seems like quite a few come without pens making them useless or people jack up shipping too much to bother. Kind of like when I wanted a kensington adb trackball and ended up getting a few locally (free) inside lots people were tossing.

If I get used to this model I might go looking for a large PC version with the digitizing mouse to work with an OLD version of DOS Autocad.

The only other ADB device I could use would be a hand scanner or webcam.
