I went ahead and bought the silentaire scorpion 1 compressor i was asking about, and its great! well worth the money.BUT, it did not come with a regulator, it has a water trap but no regulator. so does anybody know where i can get a regulator for it?
thanks

I bought mine at a Sears store, but I think most major hardware stores that sell compressors would also carry regulators and the fittings you may need.
