Bought my first two last January, a RCA 420 basic receiver, and a Mitsubishi SR-SD1 with UHF remote, and a Mitsubishi dual LNB dish. Bought a RCA UltimateTV receiver in June, and bought another RCA UltimateTV receiver ($39) yesterday. Should arrive soon. Will deactivate the basic RCA 420 receiver and run with the two UltimateTV receivers and the Mitsubishi. Love all of them.
