In large quantities I was led to understand they they were in the
$100-200 range a few years ago, sans case.

A different product from http://www.omnispread.com using DSSS and
approved for use down in your area might also fit your needs (LAWNII)

They claim that these radios can work over 10 kilometers (6 miles) using
20mW output with a receive sensitivity of -95dBm.

I wonder if that is realistic.

The more expensive ones transmit 1W.
