Get AV'd so we know you are 18+
then start looking in the classifieds and researching the different brands you see there.
Airsoft is alot like any other hobby, the more you spend usually indicates the level of quality.
That isn't to say that you can't buy a cheaper gun and upgrade it to the specs that you are looking for.
Top brands include: Systema PTW, G&P, KWA, King Arms (in no particular order)
