DSLR Camera Body Tiers

For anyone who was ever interested in or is still interested in purchasing a dslr camera, but isn't quite sure which models suit them.. I just found this:

Nikon Camera Body Table (Specs)
Canon Camera Body Table (Specs)

This is as much for my reference as it is for yours--I've never quite understood anything about Canon's organization of tiers, so these pages were helpful for me at the very least. Man.. you never quite know what you can find on wikipedia, hahah.

Also, here's a good diagram for the origins/development of camera bodies from Nikon:

Anyways, hope this has proved useful for anyone interested in one day purchasing a dslr, or just anyone confused with the differences between the camera models. :)
