I hunt for tools all the time - local suppliers, Ebay, flea markets, estate sales. Curious thing is, the only USA-made tools I find any more are at least 20-30 years old. Seems as though everything is made in China or Taiwan now. Very few tools are advertised as made in USA any more.
Harbor Freight has some pretty good "big" tools - engine stands, hydraulic tools, even a rolling gantry crane and most recently, an English wheel ($300) and a planishing hammer ($180). I wish I had known. 60 days ago I spent $1,500 for an English wheel. For the limited amount I will use it, the Harbor Freight model probably would have served just as well.
I guess that is the advantage of HF tools. In professional use, they probably wouldn't do very well but for the hobbyist, they are an affordable alternative.
