Chris,
I spotted some of these back in stock at Bunnies two weeks ago.
They have two sizes smaller is $65 larger is $85, both yellow in colour,
and have similar features as the genuine article. Jaycar also have a range of similar cases in black, but seem to be slightly lighter in construction.
Jaycar range includes about 4 or 5 sizes up to one with a retracting handle and wheels like airport cases. Jaycar equivalents to Bunnies are more expensive.
My Bunnies case is a Kincrome brand overall dimensions
430x380x154 internal 395x320x117. Includes one thin layer of flat foam, one layer of pluck foam and the top layer egg crate foam.
These are the same as in Eric's link from last year.
May want to check it floats with all that L glass inside
Cheers,
David
