I have a question: Do you want to try to use this as a real test insrtument, or as filler for a collection.

Another question and an observation:  Have you had any experience with the Tunnel Dipper?  My experience has not been good.  The couple I've worked with drop out of oscillation at the ends of the frequency range, and the meter setting pot is touchy beyond belief.
