basically whatever I found in the first gun store I stopped at that jumped out at me, realisitically If its a quality gun, I want it. at least 5 mags for it, and ammo.
i would either pick up a s&w sd9ve and ammo, or a m&p9 shield and ammo, or a mossberg 500 and ammo, or night sights for my m&p9 and ammo, or i would see what kind of .223 ar15 i could get for $500
