Cripes! You dog, you. What happened there, did you contact the seller or did the seller contact you?
I was eyeing that bugger, expected it to go up to at least $200. You got a more than fair price. Congrats!
As for separating it from the keyboard, not sure about that. Never seen one in person so I have no idea of how its assembled. If you do get it separated, you'll probably have to work out some sort of connection.
Then again, do you really need to separate it? Might be more hassle than its worth and what the heck, you do need the rest of the keyboard anyway.
Please, let us all know how it turns out and please, please, please, take pictures, lots of pictures that you post for the rest of us.
