Start with a better barrel and decent hopper. Try that for a while and spend the rest of your money on good paint, air tank and field fees. Practice, practice and practice tons more to get good and that would be my first recommendation anyway over spending cash on upgrades. The Vibe is a great starting marker as it is stock. Barrel upgrades always help most any entry level marker so thats a good start. After not playing much in over 20 years (pump guns of course) I'm getting a SP-1 or Vibe myself.
Have fun and enjoy!
