Dude, I don't even know what that means - how much would that cost? No way am I throwing away something I just bought, though. Always need a backup in case my kids scratch a lens.

Good choice, you won't be sorry. If you thought the d90 was expensive though, wait until you start looking for those f 2.8 lenses (glass) especially if you want Nikon. Not a cheap hobby you picked.

You'll take some very nice pics with your kit lense that came with the camera, and you'll learn how to use your camera with that. Learn about iso, f-stop, shutter speed. Have fun!
