I have been repairing Matbro joysticks for the last 30 years and I consider my self as an expert. I have also been service exchanging joysticks at a price of £140. Send me your old joystick and I will send you a fully service joystick by return of post. Or you can arrange to collect it from OX27 7JZ. I no longer send out a joystick on the promise that it will be sent back next day. Chas.
