Wait it out - I know it is hard but will be worth it. I wanted a mini and didn't see much locally in my price range with under 1200-1800hrs. I waited and found one 6hrs away with 232hrs and a few months warranty. It runs perfect and was worth the wait!
I agree. Wait and one will become available. True!
As for hours, 1200 max for me from an owner that is neat, organized and maintains the unit properly. Then you likely will only have small items to correct. 2000 hours I believe is better suited for a buyer who is experienced enough as a mechanic to be able to manage a major breakdown comfortably or who will budget several thousand dollars to hire it done. The exception might be a 2000 hour machine less than two years old and used in a cream puff application daily with good maintenance.
