I would say your vehicle, flying field and type of aircraft you fly would dictate your needs for a toolbox as well as economics. I myself use the same setup as Ballgunner, I have been flying for 20 plus years and seem to have selltled on this setup. I bought the Craftsman 3 drawer metal toolbox with a hinged lid for about 39.00 and it works great, It has a handle to carry and the drawers are secure when lid is closed and looks nice too. I recently saw a nifty plastic tool box with a popup handle and wheels at Wally World and thought it would be a good possibility for a model airplane tool box. I have an old maple wood flight box that just has the basics and is very easy to transport to the flight station and has everything in a compact package.
