I have two, but only use one at a time. My 80 gal. twin cylinder doesn't get fired up much unless I'm in a project that needs lot of air tools. My 2nd is a small 120v. portable that gets a lot more use for small tasks.
I bought the large stationary to have a great compressor, and was going to sell the little portable, but decided to hang onto it. I'm glad I did a it's a nice little compressor for small jobs.
