make sure it has the ability to use some sort of cable release or remote shutter release... make sure it has the ability to set the ISO.
A cable release, and the more high tech IR remote shutter release, are so you can fire your camera without causing camera shake by touching the camera body to press the shutter button. It is a necessity to get the sharpest possible images when using the camera on a tripod, and also can come in handy for some low shutter speed shots.
A typical Photo 101 class assignment is to demonstrate freezing action with a high shutter speed, and demonstrate blurred motion with a slow shutter speed. If you want the non-moving portions of the scene to be sharp in the slow shutter speed shot, you'll want to have the camera on a tripod, and use a cable release.
Most modern 35mm SLRs set the film ISO automatically from the DX code on the film cassette. The DX code is that part of the cassette that is black and chrome, sort of like a blocky bar code. There are many reasons why you may not want to rate your film at the manufacturers' recommended ISO, and if you bulk load your film it may not even have a DX code (you can get DX coded cassettes and stickers).
Anyway, there are ways to get around not having these features, but they are so basic, and really cheap to include in the camera body, that I think it's just
shameful that a company like Nikon has left them off their entry level SLRs. When I worked at the lab/camera store we'd get a fair amount of complaints from students who found out half-way through the semester that their cameras didn't have these features.
