I hav looked at the D90. Someone at the camera place I went to said they are not going to make the D80 anymore. Its really nice but may be more than I need. Hopefully I don't pass on it and then regret it. I like the HD video idea, but I have a Sony HD camcorder.
Another great link. Thanks.
If you're just looking for an all-around camera, then I'd just buy the Nikon D40 and put the rest of the money in some good lenses.
