An every day tool box from the home improvement store. Works for me! Cheaper, prebuilt, and has pull out tool bins.

A few compartmented storage cases too, for all teh screws and little bits..

Those, with the fuel bottle and starter in a milk crate works troo, and gives you a seat.

I've seen one guy use a bucket, with that fancy 'bucket tool box tote' liner thingy..

And a 'radio Flyer' red wagon, to tote all teh stuff in!!
