I agree with ExiledSeraph6, the Canon SX40 would be a better choice because it's a more balanced camera. With bridge cameras, you're going to have to sacrifice some image quality to get that extra reach with the lens because the longer barrels are going to require more light to reach the sensor. The Nikon P510's 42x zoom is tempting indeed, but you have to ask yourself how often you'll really need that extra length. Also, from what I've read (because I was in this same predicament at one point), the Canon SX40 has slightly better color quality and a longer battery life.
Neither are gonna be great in low-light, but better than <$200 cameras. The Canon SX40 has a hot-shoe for if you decide to add a flash later (the pop-ups will only reach 7-10 feet). Other than that, it may depend on what you plan on shooting.
