For Nikon:
Entry-level = D50 ~ $700 new
Intermediate = D70/D70s ~ $950 new
for used ones knock off about 200~300 depending on condition of the camera.
then you have the pro stuff:
Semi-pro = D200 ~ $2150 new
Pro = D2Hs/D2x ~ $3900-$ 5700 new
there you go.
I think Nikon's lineup and pricing are very competitive these days... good for us consumers I suppose
