Last week I received my new RX series lights, and wanted a better way to store / transport my studio gear. So I picked up an aluminium box, got some plywood and some foam.
I was dissapointed to find that the aluminium case I bought for such a good price is only chipboard with aluminium foil on the outside & rubber on the inside.
I guess you get what you pay for.....At least the lights are well protected. I won't be using it as check on lugguage on a flight or something.
