Harbor Freight.

Yeah, right.....everybody says it's junk. But look at the housings and the castings. They are identical to many of the name brands (particularly Delta). It's all made in China, so what's the difference?

Go spend $19.95 on a 4.5 inch grinder at Harbour Freight and it will last just as long as your Delta, B&D, etc.

IMHO!
