Thanks guys! Those are expensive though I've got to say!

The $102 ESC I'm good with...is there a lower cost motor that would work as well? If there isn't, then I'll just cough up the cash for that motor. I don't think they'll be having any black friday deals..or so it seems.
Thanks for the advice on staying away from hobbypartz for hobbywing systems. I'll use falconsekido.
EDIT:
Hmmm how about these two ESC's?
