That is the compressor I started airbrushing with.
They are alright but will get hot if ran very long.
A regulator would be nice if you wanted to spray at a lower pressure than what that D500 puts out, which I believe is around 20 psi or so.
Another thing is to find a small airtank to smooth out the airflow as those diaphragm compressors pulsate pretty badly.
Did you ever get that Sears compressor you had ordered?
Did you find a regulator/moisture trap for it?
