I've looked into the Stagg case, It is just a litte too narrow for the NXT, and I have heard it wasn't real durable but may have worked if it had fit.
Gollihur's has the tube case which is just like the ski case I'm using. I would live to have onw of their flight cases, whole much more affordable than the ones NS Design sells, still a little more pricey than I can afford. If I could find one used it would great.
The Pelican m3410 Storm Rifle case seems like it might works. It's hinged and has foam that can be cut to fit. Also has wheels.
It's not super cheap but closer to my price range. I wanted to explore a few more options before going that direction.
I cannot believe there aren more cases that will work with an EUB.
