99 civic rear discs

i have a 99 civ ex with rear drums, need discs. anybody have suggestions on used parts or should i definitely go w new?

Why do u need them?

Rear brakes only do 20% or so in the braking effort, thing up front, youll be better off...

If you want them to look nice...thats a different story, you can look for Civic SI 99-00 discs.
