I'll disagree with some members here. A good mentor is easily worth money, IF you want to accelerate the learning curve. A good mentor, however, not only knows his or her stuff, but can teach it in a manner that a student can absorb, and can understand. Also a good mentor should be able to see what you're doing and tell you quickly what you need to do differently, and WHY. I've seen some professional photographers give group and one-on-one sessions that were superb in terms of boosting the participants into a new orbit of skill (no, I wasn't the professional). I saw one club member go from being essentially a snapshooter, to a very accomplished photographer in about a year, with four or more workshops with this pro. This lady had the talent, but not the hands-on technical skill, and the mentoring she got allowed her to truly blossom. So... with the right combination of mentor and student, you can get very good results. As for paying money... the pro who did this charged enough to make people pay attention, but she really was doing it out of love of the field - she was charging much less than her usual professional/commercial fee for the same period of time. She told me she used to do these sessions for free, and people would just goof around and essentially waste other people's time. This way, they have a substantial commitment, and they really pay attention.
