help finding the right camera

i have around $450 to spend on a dslr. i was thinking the nikon d200,d5000 or the d80 but i dont know which one to get. i was hoping you guys could help me decide. i want to be able to use the old nikkor manual lenes. and a camera body that has good manual controls and a camera that the lenses would meter on. i want to able to do good macro shots.
