Well.. I've seen some websites with TCs where folks wound several 
hundred turns of wire on a Ferrite U core of some sort or another. I 
suppose one could find the bare cores for MOT's for instance. (or a 
cheap source for the transformers new, and just saw off the windings you 
don't need..)

Just casting about for ideas..  And expensive is a relative term.... $50 
each wouldn't be unreasonable.
