I just got back in the game after a 2 year hiatus and am in the same position as you: a poor uni student. I also have the good grace to be a talented bargain hunter. I sold everything i had when I quit, so I don't have anything left. I just bought a very reliable AEG, on here in the classifieds, for 225$ shipped with 3 batteries and 4 mags.
Keep looking, there are deals on here.
