Hi Dawn. I think Austin is a good choice, as he was trained under Hal Huggins, uses all safeties, diamondlite and doesn't insist on sedation (never even mentioned it to me, and I am phobic of the dentist). Also he's reasonably priced, even for London. I don't think he uses the vega-machine-thing, but he does know what he is doing. He hasn't used amalgam since the 80's.
