Zuki,

What is the issue with the boards that you have????

I personally use the VA76 ( for sale now) and a Triton, which is a beautiful combination!

How about considering a strong LapTop + One Man Band ( yammie styles )+ emu 1616M audio card + some VST's, and problem solved!
Every time you have the desire to change the boards, just go ahead and buy a new VST-instrument, and you got new sounds!
Endless posibilities!!!!!
