Choosing a country/hospital for DHI

Hi all. I'm 33 and live in the UK. I've finally decided to get Micro-FUE / DHI done (I need around 2,000 grafts).

Any recommendations about how to pick a country or clinic? Turkey is significantly cheaper than the UK. Within Turkey there are dozens of clinics. I have seen good things on Instagram about Cosmeticium but can find limited info in this forum.

I'd appreciate any help or reviews of Cosmeticium.

Thanks.
