This is something that puzzles me as well. I am a different case than you, since I have time to prepare. I work howevera and therefore, I do not have that much of free time but there is no pressure taking the test at the moment.
I have gone through the experiences of many GMATters here and I do beleive that you can learn on your own the vast majority of the stuff. Study and practice on your own. If, after your preparation, feel that there is no weak spot in the material, sit for the exam. If however, you feel like there are some "spots" and you want to work on them, I beleive that trying a "coach" is a good hint. Of course, you must search for it and see whether he/she will be able to focus on your particular weaknesses, the ones you feel you need improvement in order to ace the GMAT. For example, if you feel there is a problem in the CR of the verbal, the attendance of a class may prove to be beneficial. As long as the teacher will be able to focus on your particular need. Otherwise, it will make no sense.
There is no good or bad advice on your question. I think it has to do with what suits best for everyone. At least, this is my point of view.
