Thanks Valerie for the great info. I know where Elisabeth is its about 1/2 hour from me. I live on the South side or South Hills area outside of Pittsburgh. I asked around at the local health food/vitamen store but no luck. I looked in the paper and called around and did a interenet search. Thats how I found the downtown one. So what an average cost on one? I hope I can get the money together to do a few!
