If you are looking for top of the line quality and controls for your photography and excellent HD video, the P7000 is the camera to look at in the Coolpix series. If you need high optical zoom (wide to telephoto shooting), the P100 is the Coolpix camera to look at with its massive 26x optical zoom. The high-end PERFORMANCE Coolpix series usually retails in the range of 300-450$, which is on the higher side for point and shoot camera pricing.
