What case do you Glidecam owners transport your sleds in?

I have a Glidecam 4000HD we use with one of those Indian made Flycam arms and vests. I found a Husky aluminum hard case at Home Depot for $25 that the arm and vest fit int perfectly.

However I am still stumped as to a good but fairly inexpensive solution to carrying the sled. Have been leaving it assembled with monitor attached and someone just holding it carefully in the car to and from location. Not good.
