Joe is quite right, Steve, but that should not dampen your enthusiasm. 

Have you noticed that you can buy almost *any* inexpensive battery operated
watch and it'll keep excellent time year after year? Computer aided
manufacturing has brought us top quality functionality at rock-bottom
prices. The price differences are in the premium the brand name commands and
the cost of the enclosure.

The same is true for most modern microphones. The little radio shack
electret microphone elements that sell for about $3 provide high-level
output with a pancake-flat response from about 30 Hz to around 15 kHz - far,
far beyond anything even a determined ESSB enthusiast can use. So the audio
response curve is completely defined by the rig. Like modern watches, the
price difference you see is in the premium the brand name commands and the
cost of the enclosure. 

If you have an enclosure you like, you can have a top quality microphone
literally for pennies.
