My recommendation would be the K3/K3S *unless* you *never* planned to
operate at more than 10W.  The KX2/KX3 with KPA100 has significantly
more phase noise than the K3/K3S at 100W and when run through another
external amplifier (KPA500/KPA1500/etc.).

The KX3 has transmitted phase noise at (approximately) -122 dBc (@ 10
KHz) where the K3/K3S is (approximately) -135dBc (@ 10 KHz).  This
data is from the ARRL Labs as reported in the reviews of the specific
rigs.

Bottom line, the KX3/KPA100 (at 100 W) will have as much transmitted
phase noise as the K3S/KPA1500 (at the legal limit)!
