What are the main differences between clinics in Turkey?

I've been looking into getting a hair transplant for a little while now and have been in contact with maybe a dozen clinics.

All of them are what people often refer to as 'hair mills' - no specific surgeon, just a team of technicians.

I've been told that I need 2400-3000 grafts and have been offered prices ranging from £1400-3200.

My question is, are there any major differences between these types of clinics?

Naturally, I was suspect of the cheapest option but is there any logic to that? Would I be spending £1000 more just because the price makes it seem more trustworthy?

Any advice would be much appreciated!
