Like the guys are trying to tell you, upgrading a bottom line bargain basement guitar is not worth the effort IN MOST CASES. Now if you had a medium quality guitar like an Epiphone or an Agile then upgrading the pickups would be a good investment. If money is a problem(I know buying a set of pups is cheaper than investing in a new $500 guitar) then you could buy some good pickups and when you do buy a new guitar you could put the good pickups into that one. It's up to you but don't expect a drastic improvement.
