I've only got two types of cases for my 5 warmoth teles:
1 - gig bags
2 - one very strong Calton fiberglass flight case
the gig bags I use for local shows, and the Calton case is for when I fly somewhere. The flight case fits all the warmoth teles, so I just need one of those.
As for gig bags, I've been pretty happy with Levis bags.
