Which to buy Nikon camera?

Its hard to compare the 3 model I want to buy D80, D90 or D5000. Can I get some help please.
Added (1). Dolly does the D90 not have those features?

Get the D90. Or if you have more money the D7000
The D90 is the upgrade of the D80.
The D5000 has a little less features than the D90.
The D7000 is the upgrade of the D90.
D5000 versus D90
