Just thought I'd give the heads up on two cases I picked from Bunnings last night. 500x350x190 [inside], air sealed, Really robust, 4 clip-on latchets, Padded 3 levels with high density pre-cut foam (the type you can shape and cut).
$60.00 each. In comparison you'd get half the size for one in Jaycar. These come and go so I'm not sure if it's been posted before. The brand is Craftright Engineering Works.
To give you and idea of the size a G11 will fit in it with room to spare (motors removed). I just use it for adapters and all sort of other junk though that is now piling up in
various boxes.
