If the discs once shaved are within legal tolerance there is nothing wrong with using them until they warp again.

Options are the DBA 650 (oem replacement type disc), 4000 series which is still a one piece heavy duty disc or the 5000 series which is a two piece extra heavy duty use disc. Priced accordingly, they are complete bolt in replacement as per your factory discs. No need to replace the calipers.

check out dba website for more info.
