On a recent trip to Canada to ride my bike my camera (N80) was stolen. I am picking up a film point and shoot to have and mess with but want a new main camera and i am picking between these two as i am a nikon fan and they have a rebate going on. I am wondering if i should just save some money and pickup a 5700 or go all out and get an 8700. I know the 8700 has more noise then it should past iso 100 how does this compare to the 5700? I plan to shoot pretty much most things but also a main focus in biking photography.

Any opinions or suggestions?
