Search "rod rack" on the forum, I've seen some home made ones that are pretty sweet. I know of one that used coaxial cable clips from the HD to hold onto the rod. Looks like that worked pretty well and I am sure for a lot less $ then the clips you would find from a tackle supplier or a Cabela’s / BPS.
Here is the one with the cable clips which I thought was a good idea.
