Winegard or kingdome

I've had nothing but problems with Kingdom and their in motion dish. It quite working in 30 days and they would not honor their warranty because the unit had been built three years before I bought it at CW. CW stepped up and paid for the part that I installed. It's never worked all that well and recently it locks on the wrong Sat and will not continue searching. Called Kingdom and after an hour of trouble shooting, I can probably fix it for $450 in parts. Guess he did not like it when I said I could buy a new one that everyone likes for less than $450. Why would I spend more $$$ on their POS.
