Anyone have their cast iron pipes relined? Trenchless repair

Im planning on redoing one of my bathrooms but was thinking about having my pipes done prior to work starting.

House was built in the 60s, full cast iron waste and vent pipes. Haven’t had many issues yet thankfully, but I’ve read it’s better to have pipes lines before they collapse.

Has anyone gone through this, what can I expect cost wise for a smaller 3bed house.

Plumber recommendations?
