My Product Advisor - a very nice interface for helping you chose cameras and cars. I played with the camera side of it and it asked all the right questions but I felt the recommendations at the end didn't fit the bill, for example, I'd said max price $400 but it gave me 3 cameras over $1000. I had said that price was not as important as other issues but I think that is a bit OTT. SO if you use it you need to be quite precise with your answers to the questions I think.
