I have both the 18-55mm and the 55-200mm Unfortunately I didn't have the advantage of getting them in a Kit (with my D3000). The camera came with the 18-55mm, then I bought the 55-200mm separately. Recently I purchased 35mm f/1.8.
They work well in fact. IF you go with just the one size 18-105mm will limit what you can do.
Unlessyour going to turn pro then you need better lens all around.
