The D3000 is a great entry level DSLR.
10.2MP's, 3fps. 11-AF points.. Another pro for entry-level SLR photographers is that this camera has a "GUIDE" mode which kind of guides you on how to step up your aperture and/or shutter speed to what you are planning on shooting.
BUT! Do your research first and INVEST time and MONEY into a DSLR that will be worth keeping in the FAR future.
Learn from me because this is what did.. I bought the Nikon D3000, wasn't satisfied due to lack of speed i needed, returned it to the store and got the D5000. Learned ONLY after, that the d5000 didn't have the in-body focus motor so i sold it and just recently got the D90....If ONLY i knew how great this camera was before, this would've been in my hands at the start.
Like my co-worker told me a loooong time ago.. "if you are buying your first DSLR..go BIG or GO HOME, because the cheap stuff won't cut it in the future"
BUT like i said..do your research. and like Babs said, you can't go wrong with NIKON or CANON as your first DSLR. Good Luck
