I replaced both my Dometic Penguin heat pumps with the new Penguin II Hi-capacity heat pumps and the CCC2 thermostat. I chose to buy the 5-year extended warranty because it seems that if these unit fail it's usually right after the 3-year factory warranty expires! I considered the cost of the extended warranty very reasonable.
I got the units from Amazon, I think around $1200 each, plus about $100 for the thermostat. You also need to buy new condensate drain pans as your old ones will be brittle!
