If you're looking for a keyboard who are loaded with styles that sounds like a "real band",
you should take a look at Ketron as well. SD1 and SD5 are brilliant stuff when it comes to
play "as it is".
But as always, the taste are very individual, so the best solution are always to try out
before buy, your ears and taste are the right judge to ask.

Good Luck in your hunt for a new "band".
