I live in Nashville, TN, and I'm the only one I know with a Hiscox case. They seem to be pretty big in Europe, but they just typically aren't around here in the US.
There are obviously a lot of acoustic musicians around here, and I can't even count how many of the professionals i come across have Caltons. Granted, these are guys that tour a lot, but play guitars almost as nice as ours.
And a lot that I see are scuffed pretty bad. They look like they've taken a lot of abuse, yet the artists still trust them to protect their guitars. That should say a bit.
I don't think I would even mess with the thought of a Calton unless you were touring rigorously, though. My Hiscox has done me quite well.
