My go to bench grinder is a Lowes $19.99 special that I picked up over forty years ago ( Taiwan special, 6", 3450 RPM.) Wheels have been replaced a couple times. Still on original bearings, but I keep a box of 6203's in my tool box, just in case. Somewhere in back of shop, I have a Skill from the era when Skill represented quality. Paid $25 for last grinder off CL, just to use with fiber wheels for sharpening knives. It's a Delta from Taiwan.
