If you need PRs and don't want to look for Restore/Repair missions to appropriate mission PRs you can find a mission to grab an item from a crash site with Distress Call type
where it spawns an Eagle with two cutable panels and two PRs. Disembark in your SRV nearby it will allow to see if there's any normal PR (or even two) with SRV radar w/o cutting a panel.
Then re-log and collect newly spawned regulators. Do not grab mission item from the box while you're doing it or the ship will not spawn again.
I've found that it spawns a normal regulator approximatly for every 5 re-logs.
