Dr Turan/Dr Gur, Dr Demirsoy are more affordable and yet still doing good work, You really want the involvement of a Dr for at least the incision/channel opening step. Dr Bicer, Dr Keser, HLC & Dr Pekiner are the better options in Turkey and yes the pricing reflects this. Like you have found others have wildly variable results, it’s a difficult balance to get right. We can only suggest the guys doing the best work and still relatively affordable, Turan & Gur fulfill this criteria, So does Dr Demirsoy but like Yaman you will find the not so good results too.
