There's no such thing as a good, cheap zoom.

a "10x" doesn't mean anything. My main zoom is a 4x... 100mm to 400mm. a 10x could mean 10mm to 100mm, or 200mm to 2000mm.

If you don't foresee yourself wanting a more prosumer level camera, the rebel is cool, the 18-55 kit lens is decent, and you can always grab a longer zoom if you want.

If you have a budget though, just buy within that. And unless you want to drop the extra few hundred for the D70, it looks like the rebel is gonna fit you best.
