Boy, I will second that. I have a number of grid dip meters. The 59 is my
favorite and blows all the others away. It is as close to perfection as
anything should be.

The Measurements 59 is a great little GDO. Two things you must be
aware of, though: First is the coil sets are all slightly different
in terms of their stray capacitance and inductance. As a result each
set is serialized to the 59 frame it belongs with. The second is the
frequency tics were hand penned onto the dial during calibration.
Don't try and clean the dial!
