Whispy,
You raise some good points. When I was researching clinics, I had the same questions like who are these techs and how much will my result will depend on them. I think these are fair questions to ask the doc prior to deciding. Most of the clinics I consulted with assured me that the techs they use had been with them for a long time and had implanted millions of grafts. One doc even took me into his clinic, introduced me to the techs and allowed me to watch them work for a few minutes.
You are also correct that techs are utilized more in some clinics than in others. I would imagine though that the various doctors have already factored that in when setting their prices.
