I have a Das professional I bought about a year and a half ago, I have the Ultimate version as well and don't need both. The keyboard is in really good condition, but has some kind of weird blemish near the right arrow button as visible in the photo. It's really clean and works great, every switch works perfectly.
I might sell this if no one wants to trade anything for it, but since I'd just spend the money on a keyboard, I'm more interested in trading right now.
