I know him personally now....my camera was bought off Ebay I was the only bidder at $400. He also offers a warrenty and you can call him anytime for tech support. Based on the construction of the box, the extras provided, the sophistication of the sensor circuit board and the quality cameras he uses, I wouldn't blink my eyes much at $600. Especially since it's a 3+ mega pixel camera that you can use independently.
