Ring modulators

Ring (or "Balanced") modulators take 2 inputs (X/Y), and the output(Z) of
the modulator is the sum and difference of their frequencies.
So if you input a 400Hz (X) and a 1000Hz (Y) signal, you get a mix of 1400
(sum) and 600Hz (difference) at the output (z).
The result is sounds with the frequencies spaced in a non-harmonic way.
The sound is characteristically bell or gong like, but there are a lot of
variances in the effect (whistles, cheeps, etc).
A highly recommended module in a synth.
Of course, I could be completely wrong about this :)

What do ring modulators do and is it worth shelling out to build one?
