Last Christmas, my hubby bought me a workbench and BIG three-section rolling tool chest. I store my threads, stencils, extra hoops for my embriodery machine and all kinds of stuff in the tool chest. The workbench is where I store my long-arm rulers, rotary-cutting rulers, and my other two tool boxes. He bought it all at Harbor Freight.
Plus, I use the big magnetic bars on my long-arm to give me some tension when I "float" my quilt tops.
As others have said, tho magnetic bowls are a must-have.
Harbor Freight just THINKS they're for automotive/garden/etc type of stuff - they don't know that they're really a "quilters tool shop"!
