rear disc brakes on 8 3/4

i know this has been asked 10 thousend times but sines i live in Germany and everything is twice that expensive i have no room for experiments. My first intention was to go with Jeep cheerokee but there a few things i don't like. the park brake in the drums for example.

i want it cheap.
I want it solid.
i want the park brake on the caliper.
i want brake pads and brake discs from a regular car means not from the supplier of the kit.

that makes several no's for wilwood.

what about the 500 USD kit from SSBC? or summit self named kit? SSBC pads are from Ford. The discs not.

any other good kit on the market?

regards,
Michael
