im more a canon guy
i used to have a canon eos 40d that i really liked.

i dont know if you have a wallmart close to you buy on amazon its a little bit cheaper http://www.amazon.com/Nikon-Digital-...ds=Nikon+D3000
( it also depend on the shipping fees).
i honestly prefere to have one good lenses instead of 2
i dont think that you are going to use this lens a lot 55-200mm f/4-5.6G unless you want to photographs some landscape from long distance.
but looks like you have a good deal.
