I'm looking for an air compressor for occasional, not-in-a-hurry heavy duty
work. The biggest air users I'll need to run are an angle grinder and small
air hammer, and these not too often. Otherwise, it'll mostly be filling
tires, running a few Halloween props, blowing dust and water off various
dusty and wet things, and whatever else my evil mind can cook up. If I have
to wait now and then for the compressor to catch up, that's not a huge
problem.

I don't much mind if it's not portable, but it would be a nice bonus. I've
got a 230v 50 amp circuit going to the garage, along with 110v, but I don't
really want to max that out.

Oh, and I want it to last for a good long time, even if it sits idle for a
few months at a time. The only thing completely unacceptable to me is going
to use it, and it doesn't work.

I don't want to spend much over $400, and I don't mind used gear.

I'd be highly grateful to anybody who can shed some light on these
mysterious machines. I've already been burned by big-box stores selling
garbage equipment, and I haven't heard much either way on brands such as
Kobalt or Husky. I've heard nasty thing about Craftsman and CH (which I
believe also makes Husky).

Thank you for any help you kind folks can offer.

You are in two different worlds.

Each tool has an SCFM requirement at a specific operating
pressure. That requirement creates the demand for whatever
compressor output that will be needed.

An angle grinder and an air hammer use lots of air.
<http://www2.northerntool.com/aircompressors.htm> one at 8 and
one at 11 at 90 PSI to run efficiently. Whenever they give a
range on a tool, always use the hightest number.

Personal and professional opinions:
Avoid oiless compressors with a vengeance. Stick to pistons in
cast iron or screw (very expensive).

Good names: ( In order, but certainly not exhaustive)
Quincy
Ingersoll Rand
Emglow (now DeWalt, I think)
SpeedAire
Carlson Systems
If you can buy at Graingers, their Westward (Taiwan) things are
not bad.

You won't be buying new for $400. Buy a cheap electric grinder.
Forget the air chisel. Buy a pancake Porter Cable oiless and run
it till it dies.

Don't hesitate to get Campbell Hausfield, DeVilbiss, Craftsman for
what it sounds like you intend to do. The older, the better. The
cast iron pumps are too similar to make huge distinctions.
Horsepower claims make no difference. 1 1/2 HP (real) is about
all you can run on 110V.

A vertical unit takes less space, but is less portable.
