I wish someone would have talked me into a laser device years before I finally purchased one. Fast and easy with results that are easily seen. The 23C series doesn't adjust all planes easily but some shim stock will be a great help and you may not readily see the access points for each needed adjustment but commit some time to an initial set up and only small tweaks should be required after that. There's no shortage of techniques and tools for the task but the laser makes it so simple and easy that you're apt to actually keep your gear more tuned because of the ease of doing it.
