Don't forget about the VA76 too. It's much friendlier than your VA3, and easier to tweak in real time. More polyphony too.
The thre choices are top notch - better think long and hard about your performance needs because they all have diferent strengths.
Mic input?
Vocal harmony?
Are these issues?

Hi Luís,

I strongly suggest a visit to the Ketron distributor in Portugal - Manuel Pereira e Resende - S. João da Madeira. Contact Carla at 256 822371 to confirm that they have the SD1 at the shop (they normally do!). Playing it is really the best way of checking if it suits your needs.

José.

Yes... I'm now SD1 has a mic input and the vocal harmonizer so I'd really like to have those features.

Thanks for the help. I had already contacted them about the SD1 price, but I'll plan a visit later to "test" the SD1.
