As Marty said, you have chosen an excellent camera that is not only for beginners but suitable for photographers at every skill level.
I would also recommend all of the vendors that he has linked, but some of them may no longer have the promotion available for the 55-300 at a $150.00 discount that Amazon is offering. I think that the promotion was discontinued so Amazon may be your best bet. Their return or exchange policy is also better than some vendors.
Edit. To answer your question, it is a fantastic price for such a good camera and two excellent lenses.
