For what it is worth ... I have found that the KXAT1 to be more than adequate for tuning my KX1 portable antennas on 40m/30m/20m. I don't have 80m in my KX1 so I can't comment on that band. Keep in mind that this tuner (and the T1) are not designed to tune an end-fed half wave .. but an intelligent choice of end-fed wire length will give you something that will match and perform well enough to make lots of QSOs. I often use the recommended 24 to 28 foot near-vertical wire worked against about 5 ground radials, each about 16 feet long and have had very good results with this setup.
For me, the convenience of having the KXAT1 internal to the rig offsets any possible limitations of the tuning range. If you are looking for a tuner just for the KX1 then I suggest going with the KXAT1, if you want an autotuner to use with other rigs as well as the KX1 then the T1 is a very good choice (I have both). I operate portable and pedestrian mobile year round and in spite of having a lot of radios to choose from, my KX1 seems to get the most use because it works well, it is self-contained and the TFR design is very usable whether sitting or walking. I have also grown to appreciate the choice of LED vs LCD display in the rig as I have used it many times at temperatures well below -20 degrees C without any issues whatsoever.
