I am going to use an aquarium pump to aerate my next batch of beer (a
porter). I see that the homebrew shops sell stainless steel airstones
but they seem a little pricey. Would a stone that would be used in an
aquarium be sufficient or am I trying to pinch pennies where I
shouldn't?

If you intend to use a SS stone, you'd be best off with an O2
canister, rather than an aqu. pump. That's how I do it.

For the stainless stones, you may need a "deep water" pump to get
enough pressure, from what I've read. I've used the white plastic
"fine" air stones. I just siphon sanitizer through it first. If you can
connect it to a stiff tube, like a racking cane, it will work better
as the "stone" itself will float if on a flexible tube.
I would not use the "stones" looking stones as I suspect they would
be hard to sanitize properly.

The thing that I found when using them was that they fall apart eventually.
They just desintegrate. I never used one of the stainless ones but I bet
they'd be better.
There are several drawbacks that I can see with the aquarium pump method...
though I never had any problems as a result of using one. OTOH, lots of
people use 'em and have no problems so I may just be paranoid.
Cleaning and sanitization of the stone and/or hose. The hose part can be
solved by starting with a clean hose and having the pump on before immersing
it in (and removing it from) the wort. That way it is nearly impossible for
any hard to clean wort getting into the tube. Like I said, I never had a
problem but I was always a little suspicious of the stone being clean.
Boiling it was the only way that I really felt comfortable but that made
them fall apart quicker. Being sure there was nothing growing in the pump
housing (i.e. mold spores, dust, and such) that would get pushed through
that hose was another worry (of mine.) I always figured there was an inline
filter I could get to avoid it but I decided on other methods... (a drill
and a mix-stir).
More answer than you were looking for probably...

There are different sizes of SS aeration stones. One is designed for
pressurized gas like canned oxygen, but another is larger and works with
less pressure like an air pump.
The SS stone is worth it and will last forever. If you want to go the air
pump route, I would also suggest an inline air filter. They are very
inexpensive and are a good idea.

What about the scuba man with the gold chest that bubbles each time the
lid opens?

I think I'll pass on that one. They cost too much.
