I have a SuperNova2 chuck. Recently, in a brief but effective moment of stupidity, I damaged the thread in my chuck. I called around locally to see if anyone could/would re-tap the thread. No luck. Then I call Teknatool Support. They told me that if wasn't too bad, if they could make it run true again, that they would fix it without charge.
The chuck arrived last night and they have made me a lifetime customer.
