I have a Bulldog Hybrid technology 31" case, so called because it has plastic inserts to give it some rididity. It's not very high end, I got it from Del Selin in Vernon. However I took mine apart and added some internal retaining straps and a reinforcing layer of denim all around it and redid the seams so the bag's not going to fall apart. If you're not handy with a needle I'd say find something else.
