I would suggest you look on the Classifieds or Craigs List in your area, if you are set on "used". There are plenty good used AS's without the dealer mark up...just saying. We have purchased 4 AS's over the last 13 years. 2 were 3 years old purchased from private parties, and 2 were new from dealer. I found the dealers selling "used" to be quite a bit more expensive then on Craigs list or the AS Classifieds section. Patience is important.
The newer models 2015 and newer, have AC with ducted air...this is quieter then the older units when AC is running. Also, LED lighting, which saves battery, so you should evaluate if this is of importance to you or not in your decision. Good luck!
