Decent phone mount for in car video?
 

I've just got a Samsung Galaxy S3 which is too big for my old suction mount so need to replace it.

Its one of those suction mount types with a flexi arm - great for sat nav stuff but vibrates too much for decent in car video for trackdays etc.

Any suggestions?

cheers

Track days or to record dogging sessions...
