Unfortunatly, you'll not find much. Too bad Roland would not release a EM-2500 - an improved version of the 2000 - similar to the Technics KN-2600. The demand is big, and I'm sure Roland would make big money on that. (I have the EM-2000, and every month another friend calles me if I would like to sell it!)
Not that the EM-2000 has that great layout (I like much better both Yamaha's or Technics' layout, much easier and more proctical and logical), but it's far much better than the VA-7 touch screen.
