My different opinion:

I think at the beginning it is better using a real tube amp and some stomp boxes, in order to learn how an amp and the effects work. In addition you will have a better interaction between guitar and the amp. Without this experience you will never know what is a good or a bad simulation. 

Low budget tube amp also called monoprice 15.

This one and some pedals (distortion/overdrive, Chorus, Delay) is my recommendation.
