I've had the Hammer 88 (non-Pro) for awhile now. I had heart surgery last year, and it's a little easier to haul around now that we're gigging again. After reading some comments from Escape Rocks in the MODX thread, I use it to control a MODX6, which provides all the sounds. I'll probably add my MainStage computer back in eventually, but it's pretty nice to set up with a small, light footprint. As for playability, I owned a D1, and I think the M-Audio is a little heavier touch, but it doesn't bother me.
