I was looking for a MADE in USA and not "Assembled in USA" from chinese
parts compressors and came across a company called "Jenny" who was
formerly Emglo. http://www.jennyproductsinc.com/

Any opinions on their stuff or service? The pumps are still cast and made
in the PA, or somewhere around there.

I've not been able to locate any other compressors in the 2 to 5 HP range
that are actually made in the US.
