New to brushless and lost

Hi, i am new to brushless motors. I currently just bought a new t-maxx (got it on ebay for 200). I couldnt pass up that deal. I plan on getting a gmaxx chassis and single geared tranny. I just started to look at brushless motors because i want something faster then stock and im already lost. I want something 40+ or higher and am willing to spend what ever i can on it.... So about 200-300 or more. I just would like to know the fast and reliable motors i can afford and also your opinions on a controller to go with them. Thanks i apperciate any advice you have.
