Rol-Air is supposed to be good stuff. Marketed for the trades you're not going to see them in home centers, etc. and they tend to be a bit more expensive than some others.

Thomas makes some nice stuff too. Pricey though.

Mike,
Thanks for your comments. Now that I have had the compressor for a little more time, I appreciate its quality more and more. When I look at box store compressors that are larger and cost less, I see the difference in the overall quality. However, I have to say my old Sears compressor served me well for over 20 years. Certainly, under homeowner use, it was not used very hard. I had to get rid of it because I could no longer get parts for it. I paid a premium for the Rolair compressor because I wanted trouble free quality. Charles Ranheim
