I recently bought a 4 1/2" grinder from HF. This Warrior brand is their lower grade of power tools. There is also a mid and top grade in the power tool line up. This particular grinder was one of the better offerings in the cheap grade. It was on sale, so I thought I'd take a chance on it. It is rated at 5 amps so that's not terribly powerful, but it does seem to cut through gauge metal with a 1/16" cut-off wheel pretty well. I have a Clarke rated at 8 amps and a Porter Cable rated at 7 1/2...
