>But if you plan to be able to move the thing around, look carefully at how
much current it draws (usually on the nameplate on the motor). A normal
household outlet will only supply about 15 amps, which means that about 1.5
hp is all you can expect to run from it.

This is where specmanship comes in. Some (most? all?) manufacturers of
compressors for home use will stick an over sized motor so they can make
horsepower claims in their advertising. So you have a 5 horse motor but it
is only loaded to 1.5 so it doesn't pull more amps than a 15 amp circuit
will allow.
The only spec that matters is SCFM at the pressure of concern (90 PSI is
typical). Notice that the Sears unit is spec'd at a higher SCFM even
though it has a smaller motor than the C-H unit.
