the collective wisdom on this?

With moderate carpentry skill I successfully replaced 8 interior doors
without replacing the casings. I did invest about $150 in a low end
router and hinge mortising jig. Using the old door as a template, I
mortised the hinges with no problem. The tough part was ripping the
doors to the right width -- each one required about 1/4 inch removed. I
used a circular saw and straightedge clamped to the door. After doing
the first door each subsequent one took about two hours.
