I don't think what I've got is what you're looking for, but it might give someone else an idea.
My garage has exposed timbers on the outside walls. So when I decided to store my two light spinning rods for the season, I attached a couple of 1x2's to the inside faces of a pair of studs, to make a pair of arms. The rods rest across the two arms with the reels hanging between them. There's enough room between the arms to stagger reels ahead and behind each other. (If you need more room, use outer faces of the studs.) In my case, each arm is about 10", and I cut them at a 22.5 degree angle using my cheap plastic miter box. I figure the fairly steep angle helps keep them from dancing off the end when the garage door opens.
Total cost - I came out ahead by removing clutter both from the fishin' corner and from the scrap-wood bucket.
(Of course, now that I've put the rods away "for the season", I'm trying to get back to the coast again. Season? What season?)
Hope it helps somebody

PS - Nov 11, I attached some pics. Sorry if they come out fuzzy -- the only digital camera I've got is built into a phone. It's a much better phone than it is a camera, but in cases like this, it beats waiting to fill up that next roll.
