Dan,

Yes Protec does make a very nice bag. I had a protec rack bag also. But when I tried to get a protec case for the Psr9000 it was nearly impossible. I even talked to the company. Due to the 9k's 7" height finding a case was very hard. And is not made at this time by protec. Thats why George Kaye recomended to me the LEVYS soft case. But I'm sure the SD-1 being of much different demensions will fit in many other cases.
