It seems that he has reduced the price over the years. I remember his price was 65k Euro in the past. I think the reduced price is likely due to the advance of Stryde. It is really no comparison between G nail and Stryde in terms of reliability, comfort, and safety perhaps more. Mechanical clicking mechanism for G nail is also annoying and somewhat painful as compared to magnetic ERC machine for Stryde/Precice. I did CLL with Paley with Stryde.
Right now I think the only factor that makes G nail stay in the CLL would be the price since G nail is more likely outdated. However, 56k pounds, I think, isn't still cheap enough to offer an attractive factor. As I said above, you can find some doctors who offer Stryde at the similar or even cheaper price than 56k pounds. Apparently, most of doctors who offer Strdye seem to be trustworthy.
Yes, it is true that the internet is full of liars in general and some posts/comments are wrong or inappropriate. But I found this forum very helpful and resourceful as long as you read, analyse, and think enough. Many of them here try to help and to provide valuable information. I am also trying to the same at the moment, although I may be leaving here someday. CLL is a very serious thing. Prepare enough (study, think, plan) before doing it.
Good luck!
