Hello Frank (Francois?),
just to add another opinion, try to compare the Roland VA 76 and the Yamaha 9000 pro side by side and then make up your mind.
The SD1 is a good keyboard but right now is not a good buy due to a weird noise in the effect processor (which is evident in effects like chorus, flanger, rotary, etc). People living in USA and Canada don't seem to notice this noise but here in Europe it is definitely a big problem.
When Ketron will fix this problem the SD1 will be an interesting option, but not before (some people here in Italy, where I live, are already selling their SD1s, so I am afraid that right now, it is not a good investment for your money.
Andrea
