I'm ready to take the step to the phantom from my ardrone and can't wait. Couple of quick questions as I prepare to order... 1) Best place to order? 2) composite props? 3) prop balancer? And if so, would the props still need to be balanced if I were to add in the vibration isolation mount for the gopro. You know, the one that looks like to thin flat plates with a couple of rubber balls between... Thanks very much!
