I'll second the Milwaukee box from Home Depot. I have one and love it. Comes with drawer liners and has soft drawer closures.I have a Snap-On roller at top, but if thats to much money look at the Milwaukee box. Very nice and at a good price at Home depot.
If I was buying a "pro" box, it would be a Matco. Overall best designed drawers of any of them (at least when I was looking 4-5 years ago)Buy a couple of chances on the powerball, if you win tonight you should be able to afford a Snap On.
Same center and single end that my buddy has.Here's my Matco I picked up 13 yrs ago on e-bay for 6000.00 used. Nothing compare's, expensive, yes, but money didn't matter to me then. It's 10'6" wide.
I bet I can get more than that today.
