Benny, I have been using an RCA-Isotap II WP-27A. It isn't continuously variable but instead you can change output voltage in 5 volt steps starting at 25 volts all the way up,to 150 volts and it is an isolation transformer too! I think a different version on of this is a VIZ-IsotapII WP-27A. I've seen them on eBay for around $40.
