Hi,
     I make ozone generators with 25kHz transformers out of line output cores
for TVs, cost about 30 US cents each and I use 6  for a 12KV 1.5Kw
supply.The only problem is you have to buy quatity to get that price.
(1000+) I did get 100 sets -at- about $1.40 including postage, though.

Regards,
     George
