Hi I just got the M-Audio 49 key USB keyboard from CompUSA. It is $100. I love it, but I just saw the Garage Key here Garge Key @ Think Different Store and I like it because you can adjust the height and that way it'll fit on my keyboard tray. Anyway it is 37 keys and doesn't have modulation and such. I wondered which one you'd buy.
I would probably get the one with more keys and modulation and such if you aren't two concerned with portability. The Garage Key one does look pretty nice though...
