A lot of track guys and myself normally just go for Autozone rotors. As funny as it sounds, the cheap rotors last and allow you to focus on upgrading other brake pads, such as pads, lines, and fluid. It's a proven fact that slotted and crossdrilled rotors can be more of a hinderance than a help, so just going the cheap route with rotors seems to be the most economical. I've had mine on since middle of last year, no problems yet! I've got two track days under my belt! 
No warpage? Damn, my stock rotors were starting to warp after 1 year, and that was just day to day driving, primarily highway.
