It all depends on what you're using the camera for. If you're just going to use it to do shots of random things; cars, people, recreational purposes (like I do) then 3.2 will be fine. But if you're wanting to get really nice pics...then somewhere around 5 or 6 MP is what you're looking for...but then again, you're looking at a more epxensive camera too. Like I said, it's all about what you're going to be using it for.
