Is the behringer even out yet?forget the alseis (not as many options)
choice will come down to price is my guess though the M-Audio is a better deal and build quality overall
if you are looking for a better build try the Roland A-800 PRO | Sweetwater.com
if you are just looking for cheap that works (one of the few areas that there is no behringer sound) Behringer Motor61 61-key USB/MIDI Controller | Sweetwater.com
