Hey! It is a great arranger. It has been a huge success for Roland overseas. That's where the market for arranger keyboards is the biggest. But it is also a fine option for those of us in the U.S.
It sounds great, has tons of features, is light weight and inexpensive.
I will consider getting another one as backup and for portability, but not right now. I want to spend all my time and effort on the SD7.
