H-F is great for some things but I shy away on others. I bought a variable speed polisher for under $20. I can tell by the sound that the internal gears just don't mesh like those on a higher dollar polisher. If it lasts two years, I can toss it in the trash and buy 10 of these for what I'd pay for a hi quality piece.
Conversely, I wouldn't buy something like a MIG welder from H-F. I'd rather pay the money and have something that will work well and last.
