Have been using the Sony HXRMC1 for the past 3 years synchronized by Traqmate data system and charged with a simple 12V inverter so the camera stays in the car and all you remove is the memory card, in the same way you take out the Traqmate memory card. They operate flawlessly, synchronize with the data perfectly (well approx 0.5 secs delay but I believe that is true on most cameras synched with Traqmate.
The cameras are discontinued, were $2200 when they first appeared, but can be found slightly discounted as they remain very much in demand as they have a remote viewfinder and the ability to zoom the lens (making its functionality very desirable in any other application other than motor racing with a fixed focal length lens). Battery life with extended battery is around 7 hours and 32 Gig card will take around 4 hours of continuous capture.
I have a couple of Replay 1080 cameras and their picture quality is awesome, they capture sound really wall and apparently synch with Traqmate. They are inexpensive, light, small and robust. They have the ability to be hardwired to 110V/12v battery source making it perfect for in car use but its the one place I have not used them (so happy with the Sony's)
