Hey Dave, are you looking for vertical or horizontal and how many rods you looking to hang. I'm in West Hills and have made a few for friends and myself. Let me know if I can help free labor well maybe a cold beer.
Problem with store bought ones is uluas and big butt rods don't fit. These are three of the ones I have at my house. Top pick is horizontal hanging rack for ten foot rods. Middle three pics are of rack with 20 spots for 8 1/2 to 9 foot rods placed on wheels for easy access. Last pick is vertical rolling rack with 20 spots for 8 foot rods and under also on wheels to move around.

Eric, made them myself, the larger one in pics 2-4 cost about 60 bucks in wood. The other two were made with scraps from other projects, so esentially free. I've made several others for friends designs vary on needs.
