Need recommendation for brushless combo

[rnetbmet]

I want to spend about $500 max for motor and ESC and run 16cells. Don't want to ship overseas for repair. I already have Goirillamaxx chassis, motor mount, and single speed tranny (UE idler), RR slipper, MIP CVDs, RPM knuckles. Still shopping for diff's. What's the best motor/ESC combo for performance, reliability, clean and easy installation? Running Titans now w/7cell Maxamps - I need more speed and accel! Help!
