No one has mentioned Armstrong yet. They have the best ratcheting wrenches available and are the company that makes the ones for Craftsman. They are the only company making Made in USA ratchet wrenches. I agree on a previous post about the socket/open end wrenches... . these things are plumb HANDY! I have some tools from all the companies mentioned and probably 95% of my tools are made in USA. I shop around based on quality and country of origin and all companies have their advantages and disadvantages.
Yall mentioned the 3/8" impact guns- If yall like that, try the 1/4" I/R impact. I just bought one (made in Japan) and love this thing! it works great for auto trans pan bolts, oil pan bolts, etc. It has a throttle control dial to "tune" the power to avoid over tightening the pan bolts and mashing the gasket out. I have had very good luck out of I/R and CP air tools, but like I mentioned before, shop by country of origin and get the USA or Japan versions of them as they both have a "premium" (made in USA or Japan) line and an "economy" (made in china or taiwan) line.
I have had great success with Kline screwdrivers and with SK/Facom also. I prefer Snap on ratchets and have had great success with Matco sockets. I like my Snap-on "roll cab" tool box. It is the three-bay with the hardwood workbench top and has the "lock and roll" drawers, which is a nice feature when you want to move it around the shop. When I bought this box, it was the biggest they made and that was in 1996, I believe. On my service truck, I have a "cheapie" Craftsman box that has been well used and abused. it has really been a great box and fits well in the side compartment on my enclosed service body.
Only things I can mention to avoid are the cheapie import tools and the cheap lines of some of the big-name companies. I do not like Craftsman screwdrivers, basic wrenches or ratchets, but their "professional line" tools are as good as the other big companies.
Like I mentioned before, one of the best investments I have made in a tool is the Armstrong ratchet wrenches and the SK socket head/open end wrenches.
