A few years ago I bought carriers like you're describing at Walmart for under $10.00. Haven't seen them in a long time. They were made by Renegade and were called multi tackle carriers. I believe they were only the 11" box. The 14" box like the 3700 Plano can be found on Amazon under Plano Molding 974 Stowaway Organizer Rack. The smaller 11" box is Plano 964, and there is a tool box style called Stow and Go tool box Plano 1364-25. They're not $10 anymore.
