I've always gotten my moneys worth at Harbor Freight.

When I had a big sanding job with porch railing,
I bought a "throwaway" sander at Harbor for $13
Quite frankly, on of the best, smoothest sanders I've ever owned.

Same story with a sabre saw...
bought the $15(?) unit for a one-time cutting job.
Smooth, accurate, cool-running.
Much better than any of the half-dozen American brands
that I've owned over the years.
