I've been drooling over the beautiful cantilever tool boxes from Gedore and Hazet over at this thread on the Garage Journal Forums:
Cantilever Toolbox Thread - The Garage Journal Board
While trying to rationalize the purchase I stumbled across this 19" Stack-On box at Menard's for $17.99. It's made in the USA and seems pretty stout.

After a coat of paint and some leather liners I think it will fit the bill nicely for a lot less cash.
It sure is nice to separate all the tools needed for the Mercedes into a single, small box.
Anybody else using a portable toolbox?
