I want to buy an orbital sander/buffer (air tool not electric) any recommendations on brands you recommend? What size air compressor and PSI is recommended for use on this.

You are going to need a pretty big compressor to run a buffer, they use a lot of airflow (CFM) if run continuously for any period of time. I have a modest 5.5HP 30 gallon compressor and it cannot even keep up with my mini polisher (Chicago Pneumatic) which requires 18 CFM running at the recommend 90 psi. I looked up a full sized polisher and it requires 29 CFM. Best thing to do is see what the tool requires for continuous operation and don't go under that when looking for a compressor, but a buffer, along with sand blasters, will be some of the highest air consumption tools. That's why I have a high quality electric buffer and use the mini polisher for tight areas.

What are your reasons for wanting an air buffer? Viking or Ingersol Rand (sp?) both are good ones. Personally I use a DeWalt electric buffer

I'd go electric. Lighter weight and easier to use. As for Orbital, can't recommend any particular brand but I will second the DeWalt electronic speed controlled (constant speed) as I have one and it's awesome!

I like a variable speed. I like to use my glazes at higher speeds than the compounds.
