I have a clean, well maintained, ready to shoot Sony PMW-EX3 Pro HD camera for sale with a few extras. It's an excellent run and gun camera that is inexpensive to operate. The Sony pop on batteries are inexpensive, light and efficient compared to bricks. I've used inexpensive fast SD cards with the included SxS to SD card adapters and they work great. A 16GB card holds about 50 min. at full 1080p and costs only $17 at B&H.
You can use Nikon, or other lenses, with a Nikon to Sony mount adapter, or use the included Sony power zoom which is plenty good to get work done.
I am the sole owner/operator. I've never rented it, nor let anyone else touch or even breathe on it. :)
