Most keyboards use a standard 55 grams of force required to register every key, Das Keyboard has 5 different levels of force. The keys are divided into groups and their feedback springs are weighted differently; from 35 grams to 80 grams, which correspond to the strength of the finger that touches the keys. The result is more comfort for your hands.

It's a rebranded g80-3000 with blue cherries and blank keys. PCB mounted. I would probably pay max of $66 shipped for this, as the g80-3000LSCRC-2 was $67 shipped when it was available for purchase.
The seller has no idea what he is doing too:
Might want to be careful, I think that the pictures in the ebay ad (below) are of an original DAS, not the DAS II. Might be the wrong pictures but be careful.
From auction description: "High-quality membrane switch technology"So, it's "high-quality", I better go get it huh? :wink:

Honestly, though, for "membrane" rubber dome keyboards, Key Tronics are still possibly the best bang-for-the-buck keyboard. I'm saying you can get the same thing for way much less without the blank key gimmick.
