I had decided these were just too expensive. Then I stumbled onto one at a price, condition (about as minty as it gets), and weight (7.25 pounds) I couldn’t pass up. It also helped that I was able to fix my HVAC problems myself and put off replacement for a while. The setup is too low for the 9s the previous owner put on it (maybe why he sold it), but that’s easy to address. Sounds great!
