emmydotnet: Seems I may have failed to answer your compressor question so will do so now. I assume you are referring to the air compressor for charging the cylinder, so would suggest that you look into Checker/Kragen/Shuck auto part stores. They frequently advertise a small chinese "Nokita" brand twin-tank contractor-style unit for $99 which is a wonder of capability in my little home garage. It puts out 115 psi and about 4.5 cfm which is suitable for most of the jobs you'll ever have to do, except paint the car, not enough capacity/tank volume for that. Mine is wonderful, nicely compact and handy as a pocket on a shirt. I coupled it with $40 worth of good rubber hose and connectors from Home Depot and a set of Costco air tools for $89 and man I'm "Mr. Nascar pit-stop" for tire changes and everything else my old bod can handle.

Cheers,
