If you want to split it, I would like the 15/30 if you want the Variac?
I would also be willing to pay like 2/3 and shipping but $80 is just too
much for the NST alone as I have a Variac already.

Hi Daniel,

Some people use large high wattage light bulbs or heating elements in
series with the NST primary to drop the voltage and basically provide
lower
power input settings.  While a variac is super nice, Light bulbs are
cheap
and easy.

Cheers,
