Hi Jim, et al:
Oh, I suspect they'll sell MANY amps... and NOT just to Elecraft owners.
The mere fact that the KPA800/1500 is NOT specific to the Elecraft
line of products, means that it'll work with just about ANY
current-production transceiver, and will many older production rigs
as well, possibly with a slightly reduced set of available features
(e.g. auto-band switching if the rig can't provide the required data).
The KPA800/1500 CAN decode both serial AND voltage differential data
from most current production rigs, so you can actually have two
DIFFERENT rigs connected at the same time and still control the amp
with EITHER rig. That feature alone, will make the amp quite desirable.

The reasons amps seem expensive:
1) They use expensive parts if bought new. Manufacturers
can't/won't/don't use surplus, so they have to pay
full price for everything.
2) Many of the parts are expensive because they're custom and/or low
quantity items.
3) The market is relatively limited, so the engineering and tooling
costs have to be amortized over fewer units.
Elecraft has sold less than 6000 K2s since the rig was introduced in
1999. As good as the Elecraft amps
obviously are, and as much as many of us want one, how many units
can they reasonably expect to sell in the
next 7 years?

I'm curious, what makes RF amplifiers fairly expensive projects? I
admit I have no experience or exposure to them, but as far as I can
tell the two major building blocks are a power supply and a not
terribly complex amplifier circuit.
Is the bulk of the cost in the amp device(s) - power transistors or
vacuum tubes/values?
