Yeah, price what they're going for on Ebay, probably $300 is fair. Just be careful, buying batteries and chargers seperate is a rip off, hopefully it comes with that stuff. Awesome to learn with since it uses the EF lenses which all Canon digi's use. You'll be spending more on lenses than the camera in the long run, but they last and you can keep them.
As you learn, you can upgrade the D30 to something that is more worthy if you want to keep going.....there's definitely some drawbacks to it but to learn on, it's great for the money. also make sure it is in decent shape, would cost more to fix than it's worth....
and buy good lenses, so worth it....$$$
