The lowest price I've found is from http://www.efi-dot-org/  Mine came in a
couple days.
Radio Shack used to sell them, but doesn't any more.
Amazon sells them, but at $40.

Truly an amazing device (if you've ever had to do these measurements the old
way, you'll really appreciate it).

Terry has a bunch of stuff on hot-streamer where he reverse engineered them
to a certain extent.
