I'm not sure if Costco has toolboxes any more. I have a Kennedy machinist setup that I bought in 1977 and I got tired of one of my co-workers hounding me about how full my toolbox was, so I bought that one at Costco.
The Kennedy doesn't have the ball-bearing drawer slides that the other box has. That is worth having, I think, but the cheaper boxes are made...cheaply. As long as you keep that in mind, you'll be OK. If you want to buy a lifetime box, go with an old Craftsman or Kennedy. This is my buddy's box...it's been through the wringer, weighs a ton, but still rolls around so easy and the drawers...chock full and still glide smoothly. Of course, this isn't the workbench style like you are after. There's also Snap-On...a lot of the jet engine mechanics had those, I think it was a prestige thing, there was even one guy who had two of them, back to back. One side was a dedicated audiophile stereo system!
