I have a good friend that collects Calton cases.....he's got more of them than his high end acoustics. I had a couple of Caltons when I was flying with my expensive acoustics back in the day and it was pretty cool to be able check your guitar case into luggage with a $6k Collings in it. Those things are indestructible.
But these days, since I build more guitars than I buy, and since I NEVER play outside of the house (except virtually on Youtube

)
AND since I live in Florida where the relative humidity keeps all my guitars nice and happy hanging on the walls of my office, I don't sweat cases anymore. More trouble to find a place to store them. Now guitar shipping boxes, that's another story, I have a crap ton of them up in my attic because I KNOW how fickle I am.....and likely to rotate out my whole current collection in horse trading within a few years. Heh.
