Very interesting. Their US General toolboxes are full of win. At least as good as decent grade Craftsman or Kobalt boxes. Not as good as a Snap-on box but the chances of me paying 4-5 figures for a box with no tools in it is slim to none. The whole concept is ridiculous. Last box I bought was a 30 year old Kennedy. Probably be the next box I buy too.
I'd say the US general toolboxes (not the cheapest ones they have) are way better than the current Craftsman (which really suck) or Kobalt boxes. I'd say they are edging up to the big boy's boxes...not as flimsy as the cheapies.
The thing about Snap On is you gotta remember they are very much geared to the easy credit model...the tool trucks will give the mechanic a huge amount of credit and let him pay it off weekly at "reasonable" rates. They'll sale a guy a supposedly $15000 Epiq tool box and let him pay it off at $20 a week.
Many of the hand tools they make are excellent quality (and can be obtained on eBay for half the cost off the truck) but most of the other things they sell (air tools, welders, shop equipment, etc) are better obtained from other sources, because honestly that's what Snap On does themselves with many things.
Harbor Freight stuff seems to be getting better and better, as they actually strive to improve items. Many other chinese made tools from other sources seem like flimsy crap right off the bat but you can tell the HF tools are a higher level of quality.
