there is not really levelling up in airsoft pretty much all guns perform roughly the same out the the box. more money will get you nicer parts more features but you are not going to see amazing leaps in performance. what do you actually want? another Armalite? personally for that money TM P90, TM AUG High Cycle, 2d hand TM G36 recoil, CYMA M14 (well under budget you could get multiple guns).
