most hardware stores sell 2000w elements as well
BTW, the max you'll be able to get is not 2000w, but 2250w (blichmann boil coil) and you'd have to be on a 20amp circuit as well.
to the OP... if electric is not your strong suit.. i'd get something pre-made, like colorado brewing supply stuff. it's setup and ready to roll.
