David,
A very good analysis.
I agree completely that the K3S is an upgrade to the K3, and an existing
K3 can be upgraded to almost the equal of the K3S - the RF board cannot
be upgraded, but just about all the other changes can be incorporated
into your K3 should that be desirable.
I consider this upgrade to be similar to what happened to the K2 at
serial number 3000. The boards were redesigned, and all the prior
upgrades were incorporated into the new boards. The older A level
boards could be upgraded with the kits provided by Elecraft, and there
were only a few minor differences between an upgraded A level K2 and the
newer B level.
I believe Elecraft is unique in allowing customers to upgrade to the
latest level by providing upgrade kits at a modest price.
73,

That's the "trap" that other manufacturers get you into, but not
Elecraft. The TS-590 may be a good example. The new "SG" model is
significantly improved. I think there was some sort of upgrade
process for older models, but I don't think it went all the way to
"SG" equivalency--not in the way a K3 can be upgraded to nearly
identical specs to the K3S. Anyway, if that is not a good example,
there are plenty of others that do make this point.
