I ordered a DVD from Kurv Studios and they are not responding to my phone calls because their phones are not in service. Beware. I emailed them about my order and have not received any response.
They sent me an email 9/13/09 saying they would credit back the shipping cost on a DVD. Still waiting… 
I am worried.
If you are looking for some excellent ZBrush 3.5 video training, and top notch service, here’s the ticket:

even better:

I have purchased training DVD's from other vendors, but they don't come close.
Good luck with Kurv.
