XP Pen, by Deleter(yeah, the bottled ink company). I got mine off of Akadot retail(
http://www.akadot.com/ ). But they go on back-order allot and I'm not really sure that they're selling them anymore. But generally I paid $110 which was pretty cheap at the time. I still use it even though it's been pretty abused by my sibling... Anywho you can probably find a better one out there for cheaper now days. Mine is 3 years old...
