aj;
Im not sure if I to late with this info, only just had the time to go over the forum more detail than usual and found your post.
I am talking from experience
it is better to get a light industrial compressor. I have just replaced my hobby compressor with one.
As where to find them here in Australia - Kmart occassional has them in there tool department (that where I obtained mine from earlier this year at a cost of $120). Other possiblities are Bunnings Hardware , Mitre Ten, and other large hardware stores.
As shermanfreak recommended get a comination pressure regulator and moisture trap, they can also be found at the hardware stores.
Even though it a little late hope this helps.
