i thought for sure there would be more around this area. i know there is one in texas, florida, and new york. the one in texas charges $2,000 each. another dentist in north carolina charges $2,500 each. the one in florida charges $440 (that was 2 yrs ago and it was to re-do recently done cavitations, which was wrong, as they were done a month prior; he was trying to make money). hal huggins might know of some. they will cost you quite a bit, though, i imagine.
