Brad, I have a Curtis cab with heater and I really like it. I have not had my tractor for a long time ( since last Dec.), but there were several times when it was nasty out last winter that I would not have been outside doing tractor work without the cab. I am outside alot when I am at work so it's not like I mind getting cold. Even when using the backhoe with the back flap open the cab gives welcome shelter from the wind.
It was nice this summer to have some shade and be out of the direct sun, didn't need the heater.
I am going to add a windshield washer as the windshield picked up quit a bit of dust when doing alot of loader work.
I will see if I can get a picture. If you have any questions I would be happy to help.
