I've had one of the HF buffers for a few years. It's really not bad at
all, just not excellent like the Baldor stuff is. The left-hand arbor
comes with a GWOUH (Grinding Wheel Of Undisclosed Heritage, pronounced
"G-Woo"). Call me a coward, but I won't even spin up one of those to
test, I just throw them away. I put a wire brush wheel on that side,
which I've really gotten a lot of use out of. The tool rest that comes
with it is quite flimsy, and the plastic eye-guard didn't cost a lot
either.

If you want to buff and maybe do some wire-brushing, it's hard to beat
for $49. For grinding purposes, though, it lacks a sufficient stout
tool rest, eye guard, and dust discharge port.

HF stuff is great in the right context, but to paraphrase Mr. Eastwood:
"A man's gotta know his tools' limitations."
