home garage compressor: how many CFMs?

[james accordino]

You said you're NOT going to run sanders.  DA's
especially hog the air.  I use don't want to do any
sand or bead blasting, either one will be fine.  I
can't think of any other tools or tasks that my small,
intermediate compressor can't handle.  It's just under
your "B" choice.  But it IS highly portable (though
not as much as a "pancake").  That's how you end up
with 4 air compressors.  Best advantage to largest
compressor is it runs less often for shorter periods
of time.  That's important to me for a number of
reasons.
