Scott,

Finn's method would be excellent, however, you may not
have the experience or parts to make use of it.  

Another idea is that you could build Terry Fritz's TCT
(tesla coil tuner) and use that to determine Fo.  It
is simple, and the plans are on hot-streamer
somewhere.  I am sure someone on this list could point
you in the right direction...I have it on my HDD too.

A nice scope is the Velleman HPS10 personal scope. 
It's small, battery powered, and actually does
frequency calculation for you for when you are in a
hurry.  Great price too!  Don't go solid state without
it!  I love mine.  Plus I have an old Tek too.

-Brett
