Yea, it's tough to find cases for this synth. Did you try

That would probably be expensive. I ordered a custom gig bag for my Indigo 2. I think it was from a place called gator cases but I'd have to find the info. It's a good case, nice padding and great for transporting the inst. It wasn't expensive either, around $55 including shipping. But this is a gig bag, not a hard case. Would be cool if Access made some. I'd definitely buy one.
