look into the JMR MB1000 there is an artical on pirate 4x4. I have a pro tool 105 and it is nice but the bearings and bushings in the JMR MB1000 are a definate upgrade.
I wouldn't think that it takes too many apms to work. I have a 16 gauge wire and a small switch and it never heated up. It is a good idea to put it on a keyed source. If you want a lot of good info on the york compressors look this link up http://www.jedi.com/obiwan/jeep/yorkair.html
