I had my dealer check and there is none within 300 miles of my location.Apparently everyone has bought them up to avoid the new epa mandated engine.
The 3540 is a fine machine. I have a 2008, 40 series i use in my business, its performance has been flawless. I advise you to search for a 40 series (new) and compare them. There are things i like about the new series, but there are some things i really dislike as well!
