These are my main toolboxes. I'm not going to show you my shop because it is a disaster and needs a serious reorg. I emptied a 1,000 sq ft storage building a couple of months ago and everything I kept got thrown into the shop...
These are old - really old. The newest top box was probably purchased in 1978 or so. The others came from my Dad's place. One bottom box he gave to me, probably in the '80s, the other set I got when he passed away. You can't buy anything like this anymore. Even the best, most expensive toolboxes are made with much thinner-gauge metal. My son used to shop craigslist for toolboxes. He found a couple of nice ones for about 25% of retail. I would definitely shop used before making a purchase. Nothing wrong with new, but auto mechanics tend to get into situations and have to sell and you can often find some deals. He picked up a Mac Tools 11-drawer 1000 series roller workstation for $900. I'm not sure but I think those things go for ~$4k new.
Also, I've gotten some killer deals at Sam's Club from time to time. I bought a very nice metal workbench with a butcher block top and two matching, diamond-plate storage boxes that roll underneath it (also butcher block tops) a few years ago. Prices are higher now, but even so what I got them for was a steal - I think $250 for the whole set. I ordered a same-size metal workbench top from Sears for about $100 and swapped it out to save the butcher block.
