Source for power supply parts

Does anyone know a source for good quality power supply transformers as well as complete power supplies? I found Astron as one potentil source. Audio Consulting of Switzerland is "good" but they charge $3,400 for a transformer. Michael Percy does not sells these types of components either.
I realize this is an audio site but want poeple to know this:
My brother in law is 45 and got tongue cancer. Very unpleasant therapy as you can imagine. At an "A-A" type group session for recovering cancer patients, he found others there who also got tongue cancer. Turns out they also were sucking on breath mints all day. You won't hear this on the news yet but there is some connection between breath mints causing tongue cancer.
