MOTM

I've not yet found a keyboard controller that has everything I want. 
I picked up an MK461C from M-Audio a couple of years ago that I'm 
reasonably happy with. Pros: 61 keys, pitch and mod wheels (I hate 
the Roland/Korg levers), lots of knobs and faders, very light, cheap. 
Cons: no aftertouch, very cheap keyboard feel, does not include power 
supply (they think you'll power it from a USB connection to your 
computer) but you can pick one up at Rat Shack.
