The tuner in the AM21 and the Hr20-700 is pretty crappy. I've been using a HR10-250 for years, and it's not known for the quality of it's tuners, but in my setup it beats the AM21 easily.
I just got the AM21 last week and had the HR10 and the HR23 running side by side with exactly the same signal. The HR23/AM21 setup broke up when the HR 10 was rock solid. The tuner in my Sammy Pn50A650 beats either hands down. Just added a HR20-700 and it's about the same as the AM21.
