Got mine from TSM mfg. www.tsmmfg.com They get rotors without center or lug holes machined, then machine them to fit your application. They make their own caliper brackets, and use GM calipers (with or W/O e-brakes). The kit is about $275 without calipers. I've had one on my Jeep for 7-8 years with no problems. Best thing is, they're only about 1/2 hour drive from my house, so I got to pick them up and meet the builders.
