My advice... don't rush and buy "uber" gear...
If you want to get good, start a low level and build it up from lv1... use the 2k to buy things like combi/lens for a few months untill you get higher and decide if it's the right game for you
Ofcourse no one can tell you what to spend your money on, but trust me.. real life experiances tend to outweigh those in game by far. You're either loaded or very sad to be planning to spend that much
