[TMC] TMC-SBT-1KB

[James M. Walker]

Probably won't find prices. Not unless you can go back in the files of the 
GAO,
who is the purchasing agent for the State department, and the Military. They
paid the bills for the equipment. Might have a listing somewhere, but might
not be on the web, old data, and they have a lot of data.
