I bought one from RoqSolid in the UK -- took a while (about 8 weeks I think?), but was able to configure exactly what I wanted for my SC:

I got the Barefaced cover with my new Super Compact, then I bought a used SC and got a cover for it from Tuki:
Barefaced Bass Super Compact Cabinet - handle side up - Padded Cover
It's really great but I kinda prefer the barefaced cover as it fits better. It costs more for a reason, as all of the 'bends' are stitched so it stays perfectly square and fits better. The Tuki is made more like a 'wraparound' with only the edges stitched and it tends to pooch out and does not fit as perfectly, but it's not a huge difference. The Tuki is 100% fine, I just prefer the Barefaced cover.
If none of that makes sense, I can get some pictures to show what I'm talking about.
Thanks to all for the advice! I used a Meinl cajon bag for carrying my One10, so I was hoping there was something like that out there for the SC. Ideally I'd go for the Barefaced cover, but I can't justify spending that much on it.
