[Elecraft] [KX1] Auto-tuners for KX1

[Phil Hystad]

So, what is the better way to go.  There is the internal KXAT1 auto-tuner for $99 and then there is the external T1 auto-tuner for $136.

Are these the same or equivalent tuners?

What is the SWR range for these?  10:1, 5:1, or 3:1 or whatever?

Is there an advantage to the KXAT1 other then the fact that it is internal?

Thanks for any answers and comments.
