At saber class, I noticed one chap used a plastic rifle case. It was too short for our Grand Master or Savior, but fit his Emperor's Hand. Said he paid $10 for it at Academy.
Today, I did a quick search revealed a $16.99 case that holds 48". guess how long that Savior is? 47.5
I bought it and am gluing the foam padding in (it's loose and flops out otherwise). But other than that, it's reasonable ruggedness and can hold 2-3 sabers and a couple tools. Better than using the cardboard shipping box my wife's arrived in.
For other gear, I bought a $35 duffle with a big side pocket, wide front pocket and main area with a mini uvula pocket for phone and keys. Fits two pair of lacrosse gloves in the side pocket. With a pair of shoes in the main area, I think there's still enough room for a fencing mask when I get one.
I'm carrying for two people, but I don't see individuals bringing more than 2-3 sabers to class. Not the same usage requirements Lady Revan has
I'll try to get back here to post a pic when the glue is dry...
