Good thing this isn't posted on "Photoforum" or "Fredmiranda"

While Canons INCR (In Camera Noise Reduction) is better, Nikon's processing software seems to have an edge. The images clean-up better IMHO,. Also I prefer Nikon's ergonomics. That being said, I
use the EOS system.
You should be able to lay your hands on a 2nd or 3rd generation DSLR for around $2-$300, though it might have seen a few shutter clicks.
