Just an add on to tool storage, i have several roll cabs, they are base units for mechanics tool boxes, also a couple of midi boxes, these can sit on top of the roll cabs or on the bench or shelf, bought new they are fairly expensive, £50 + for the midi's and £80 - 100 for the roll cab, on ebay they can be had for half that, BUT, the do come in different sizes, width and depth so watch out. If you have lottery funding, go for the Snap on gear, fantastic quality for a price, £5000 will get you started!!!!
Joking apart,
