Hey Mark
I've been using Roland since last year when I decide to get SD1+.
For beginnig I was disapointed for the luck of patches...from 3600... VA76 to 385 or someting...but why thousands when less but better!
Now,after one year of using it day by day I must admit is a perfect keyboard for Live playing.Very present and natural.Don't forget the vocalist and sampler...really helpful.Check waht can be done with samplings http://home.no.net/viocaia/ketron.htm

Good luck
