No one else has said it yet,so I will say it.
No tuner is better that its antenna and the quality of the broadcast signal.
It is by no means the best,but I like the flywheel accuracy tuning on my Matantz ST-17. It's connected to a chimney mounted,turnstile style,multi-directional antenna from Radio Shack. It's a good antenna for about 30-40 miles,line of sight.
