When ever I work with PVC I always use my 12" sliding compound miter saw to cut it. I insist this because it has a cleaner edge to it and makes for better gluing. I also insist on priming the "Lip" of the pipe as when you push it into the hub the glue builds up around it and seals it better. I also will NOT tolerate any excess primer to be seen. This is just crappy looking and makes the inspector look harder at a job. I also like to wipe the joint with my finger around the hub after I set the pipe. This may sound a bit extreme, but I rarely have any trouble with leaks. Also as someone else had said, the inspector comes in, sees a neat job, and things go smooth.
