Don't settle on that BSP just yet...have you checked out the Keystep Pro? Imagine two BSPs jammed into the same case with a velocity-sensitive keyboard, user-programmable arpeggiator, dual expression controllers, loads of I/O. And just $140 more.

Even with two BSPs and a Keystep on hand here, that KSP is something else! And I can lock all of that crap up to most anything, since it all plays nice with +5V clocking. It's a decent size-fit for a 104 hp cab, too.
