I started with a cheap ($200) Husky box that came with a nice socket set that my parents bought me for me hs graduation, then one day the Cornwell guy offered me $400 trade for it so I said deal! Ended up with what is basically a cart sized full box, I'll get a good pic of it sometime. It's small but since I stopped turning wrenches for a living I quit buying tools. It still lives at the dealership for when I wanna go over and tinker.
We've a couple Craftsman boxes with the basics at home and a big locker to keep all the misc stuff in.
I really wish I had a pic of the Snap-On box the local college auto program has, they got it while I was there, it's a black 144" series, that's right, 12 feet! It's HUGE and awesome. It listed for something like $25k but the college got in dang near half price, still a lot of money, but it is a lot of toolbox.
