[Elecraft] Considering KPA500/KAT500 Combo with Flex 6500

Hi... with all the hoopla over the new $7K Flex amplifier I was feeling a
little power envy so went on a search for options. I own an Elecraft KX3
and absolutely love the rig quality so I'm thinking about the KPA500/KAT500
combination assuming I'll get the same quality equipment.

Is anyone running this combination with the Flex 6500 who might share their
thoughts, configurations, hints & kinks?

I'm thinking the combination makes sense for me because (my decision
points):

1) Being a low power operator, 500 watts seems a lot more manageable than a
nuclear powered 1.5 KW setup. It seems like a good, safe step.

2) No electrician required. I think I can run it off 110 VAC already in my
shack.

3) If I understand correctly, there is little or no integration effort
required. I'm looking at putting it inline with the RF path and adding a
PTT connection. Voila.

4) The KX3 is able to easily tune my 600 ohm ladder line fed (via 4:1
BALUN) 80 meter dipole on any band so I would guess the KAT500 wouldn't
have an issue.

Is there a reason I shouldn't consider this setup with the Flex? The only
other thing that caught my eye was the ACOM 1010 which would also require
an external tuner.
