Rag's sounds like a winner, but, if you're cheap, don't want to do any work, go to Lowes, Home Depot, Wal Mart, K Mart, ask them for the wooden displays that the flower bulbs came in. I was getting 3 a week from my Wal Mart. Made everything from kids bookshelves, toy storage, outdoor garden junk storage and yes, ball racks.
The ones I got were 1X4's with 2X4 bottom frames. 4 shelves, cross frames on the sides and back, holds so many toys, books, and 20 balls per rack. You will need something like a pick up to haul them in but the Wal Wart I got mine from were throwing out 2 to 3 a day for 6 weeks so getting them was easy.
Just passing on info, Good Luck.
