Most household outlets are wired for 15-20 amps. Let's say you were getting
all 20 amps out of your outlet. 20*110 is 2200 watts, which, assuming 100%
efficiency, is just under 3hp. I think that's why you weren't that
impressed. I went from a Sears "3 hp" (probably close in actual power to
your 1.5 hp CH) to a 2 stage 6 hp Devilbiss ($600 very slightly used) last
year, and that difference indeed blew my socks off. Once that 80 gallon
tank is full of 175 psi air, you can sandblast for quite a while before it
needs to run again.
You should probably experience a better example of a "6 hp" compressor
before you talk yourself out of wanting one.
