I have to admit to operating a tiny bit of SSB.  I had an old friend 
(since gone to his reward) who had forgotten the code and I needed to 
get on 75 meters to work him.  He gave me one of those Radio Shack 
electret elements.

I got a piece of 3/4" or so PVC and a couple of PVC pipe caps, drilled 
one cap for the element and stuck it on the pipe.   I drilled the other 
for the cable on the other end.  While I was in Radio Shack, I picked up 
a cheap but solid mic stand and a little foam gadget that is used to 
reduce "plosive" response.  It fit perfectly over the element.  I put a 
bias resistor and blocking capacitor in the tube, and hooked it up.  I 
painted the thing flat black.

It looked totally professional and got reports equal to or better than 
various other mics that I tried.  The total cost was about $10.
