Alternative Bag/Case for 4ft Kino?

[Roger Alexander]

I recently bought a new 4 ft. kino. I don't want to spend $200-$300 on a case to carry it in. I'm looking for a cheaper substitute that will fit the dimension of the fixture just to be able to protect it from scratches and preserve it looking new (assuming I won't drop it on the ground at any point). I'm not so much worried about shock absorption, mainly just a general protective covering. Any suggestions?

Army surplus store might have a big enough duffle bag.
