I have recently done the same thing you have done. Sold 99% of my imported hand tools on craigslist, some for more that I paid for. Now virtually all of my hand tools are American made. I have a few taiwans and what not, but no chinese garbage. Sold my big 227 piece kobalt socket set, a boatload of chinese garbage kobalt pliers, a bunch of chinese assorted junk. Now I have Mostly craftsman, with a good number of channellock, estwing, etc. I am a LOT happier with my American made tools. They dont start to rust right when you open the package, they have a sturdier feel to them, and best of all I get to read MADE IN USA when I pick up a tool. Sick of all the chinese ****.
For tin snips, I would go with midwest. Great product. Made in the USA. I got mine at sears. Wiss are nice too.
For power tools, SOME Milwaukee tools are Assembled in the USA. You have to check the package. Dewalt is mexico/asia, depends on the tool. Mexican Dewalt seems to be nice, plus I would rather have mexican than chinese.
Other than that I dont have a clue.
