* A Personal note on the. New Studio Logic SL 73 or 88. I find that Outside of the Weird 3 X/Y Stick Controllers(I want Wheels).
The SL-73 at $499 is a killer deal. Top of the line Fartar keybed. Wish it came with Semi Weighted keys. And most probably . The 1 I will purchase.

While this list is more than a year old. It is Still a great Source of info When looking at Keyboard Manufactures and the Keybeds they use.
Keeps you from Looking stuff up or asking the Company. Can't guarantee accuracy, but here it is:
