Well from the response I think you are wrong there Mr. Lau, Gary! State of
the art TC's are not yet as powerful as the Buggy Whip old tried and true! I
do not intend on getting rich from these, that would spoil the intension of
supplying an affordable solution to the masses other than spending countless
nights soldering MMC's together. Ask Jim Mora what it is like, He is
building a massive one now!

Hi Gary,
 
It's true that probably no one is going to get rich doing it, BUT....

Probably because oils from handling contain conductive salts.

The manufacture and distribution of Model-T Ford parts is still a 
million-dollar business in the U.S. 
 
Ebay item # 260063956614 is a brand new buggy whip.

Forty years ago, RCA announced the demise of the vacuum tube  amplifier.
Last year,  audiophiles sent over a million dollars to Russia because 
they were too "backward" to stop making tubes.

I did, five years ago, from someone on this list, and it's still  going.

The one I bought also looks cool!

Good points to consider!
