Rugged Case for HP-71B

[dhe]

As part of my adult continuing education, I'm know the new owner of a gently used HP-71B. I've already pulled down the most excellent HP-71B and HP-IL Compendiums.

I'd like to take this computer with me, but I fear a soft case, might not give it the protection it needs and deserves. I know from the HP-71B Compendium a hard/rugged case was created, but until I find one of those, has anyone found anything that works well for them, that is currently available?
