[Elecraft] KW Amp Prices

We mostly live in high rise multi-storey condominium in Hong Kong.  Outdoor 
huge antennas are definitely out of question.  While most of the time using 
QRP, QRO is not a sin especially in some marginal and difficult situation. 
In case necessary, I use my K2 to drive my ICOM ICPW-1 to get about 300 
watts.

It is nothing wrong with an AMP kit.  It is educational.  How to use the AMP 
is a matter of operation practice and the AMP itself is nothing evil.  I am 
looking forward to having an AMP Kit which I can build and maintain.  I love 
my PW-1 but it has to be sent back to factory if there is anything wrong.

Shall we think more positively?  The skill learnt from building an AMP kit 
should be different.

It is my 2 cents view.
