Viper Case (non-esp)?
SKB TSA CASE for a thermoplastic case ( skb 61 is supposed to fit a viper )
G&G for a wood case
Personally I own both, as well as the basic esp case, the vintage style esp case with the white piping, The cases with the metal plate logo. I have one nicer esp case with a metal logo that was made by g&g.
I think its a custom shop case. I also own tkls, gators and a couple generics.
Hands down I would go with the skb, if you don't mind the chainsaw style and lack of storage.
the g&g is hard to beat if you want a full size or a vintage look.
also the muscians freind cases are good cases for cheap
but not really in the same ball park.
