Dont own one yet.....but as soon as I have enough cash I am getting a VA7 or VA76.
I personally dont like Yamaha/Solton/Technics music styles.
The Roland VA series have over 3500 different sounds.....Yamaha etc dont even have half of that...
Also the VA series sound quality is (in my opinion) the most realistic....
Check out this interactive demo...it will take a while to load though ...but you'll be able to press all the buttons on the va7
