I have cut my own hair for years and years now, about as long as I have been slowly balding. It looks terrible if I just let it grow. It takes some practice, and a hand mirror is a big help for the back. It feels good to save the $10-20 it would cost for a "professional" haircut. Last year I received a Flowbee, so I can trim it all to an even length. Today I am going for a 1/4-inch trim, which about matches my 2-week unshaven facial hair. My head will be like a big kiwi.
