The D5000 is a great camera. It has a lot of the same internal parts as the D90. Check out the review on
www.kenrockwell.com. He is a Nikon FREAK! There are plenty of lenses available that work well on the D5000. The only thing I miss is that it does not act as a commander for off-camera speedlites. Oh well, it has been a great starter camera for me!
