I’m also from Hungary.
I recently received the NExt implant. I found 2 contact details on the walletmor site. At the plastic surgery the implantation costs 60.000 HUF, at the tattoo parlour you can expect to pay around 10000 HUF.
I got it at the tattoo artist, the guy was very nice. The only problem I have at the moment is that I can’t quite read the implant, I have an open topic about that. So I can’t fully recommend the tattoo artist yet, but it’s worth a try.
