To be sure, there are some tuners that are better than others. N4XM's
looks like the best of the bunch. But a little extra work outside means
less expensive shack heating inside.

Actually if you added higher value capacitors to any of the other T network
tuners they would work as well as the Xmatch.
If you read carefully, you will see it is a T network tuner with large C.
That hurts
ten and fifteen meter performance, but improves 160 a whole bunch.
The problem with most T network tuners is they do not have enough
capacitance,
so Q is too high on 160. This was all covered in rec.radio.amateur.antenna

Meters, switches would not hurt, so what about the Heath SA2060?
Anyone have performance data?

Look at the amount of capacitance. That will govern 160 performance
into low impedance or capacitive reactive loads.
