BIG difference between DISPOSABLE tools like die grinders ---- and a lifetime (10 to 20 years worth) of use from a good machine.
Die grinders for $20 at HF are fine -- except that you should wait for when they put them on sale at $9.95 and buy a half a dozen of them like I do....
I buy hand tools from Snap-On

They'll last you a lifetime ---- But I do not buy rebadged welders and air compressors... for twice what they're worth...
