I had to replace my line about 5 years ago, same problem. I used ARS. They did a trenchless repair. Dig two holes, one at the house and the other at the main in the street. They have a device that they pull throught the old line. It breaks the old tile line and pulls in a new seamless line. There was no damage to the lawn or anything in between the holes. The distance was about the same as yours, cost was about $7000.
