lol, it's up to your ears to decide to be honest, hit up local shops and startin hittin stuff

Some recommendations on brands though that have good sets on teh cheap, PDP,
Gretsch,
Ddrum(not a personal preference till you get a higher end set), if you really have to keep everything under 4-500...pulse...but get new heads with it. Cymbals, again up to your ears to decide, but starter cymbal packs I'd recommend would be
meinl mcs or maybe
sabian b8's or
zildjian zbt's...I'd take the mcs over any, but the b8 hats have a perty nice sound but they're a "pingy" cymbal line in general.
