KNO3 have you thought of selling your T125, say if you don't use it, given all of Karsten's other works you have?
Hello Steamytiger, I haven't thought of selling my turbine and it is the only product made by Carsten Gintschel that I have. Maybe you are thinking of someone else?
Anyway, if you want his turbine, I encourage you to contact him. He might even have some in stock. When I bought it from him the price was very fair, he also customised it on my request.
If you need his email, contact me by email or pm.
