Thanks Alan.  The MFJ meter isn't available anymore either.

As to my radio, my station is a mix and match affair.  I have four 
two-meter transcievers and two TNCs and a tracker.  I have cables made 
up so that any TNC/Tracker can drive any radio.  Sure makes setting up 
the correct deviation interesting.  That's why I was looking for an 
inexpensive meter.

Thanks again,
