It's a lot of money, and I'm kind of skeptical. The reason I would be getting the fit is because of the constant lateral knee pain I've been having.

The reason I'm skeptical is because my trust in other people's knowledge regarding the solution to knee problems is very low. For example, my running knee injury (not the cycling one) was misdiagnosed originally, and with a lot of professional help, nothing has fixed it, or improved it really (I'm only 21, and it's approaching 8 months). Not to mention the fact that other people in my family have had little luck with doctors.

So I'm somewhat hesitant that the person performing the bike fit is going to know all the subtleties and intricacies of a human joint system so complex that it baffles the most knowledgeable experts on the subject.

Sure, there's anecdotal testaments to the "professional bike fit". It worked for me! Well, that's great -- but did it really work for you, or did your injury just resolve itself with enough rest and time?

And what makes a bike fit so magical and mysterious that it can't be performed by someone at home? Is there like a 1200 page book describing the various forces of different muscles and joints and how they interact (along with a finite elemental analysis simulation), with probabilities of improvement from each positioning adjustment supported by a large sampled study? Video cameras with 1000 fps to observe every subtle misalignment and its effect on everything else in the setup?

Sorry if this is coming off as pessimistic, but I kind of have this feeling I'm going to drop a large amount of cash and be disappointed. Like I said, I'm still considering it because I'm running out of options and I don't want to give up cycling, so if you have any suggestions, I'd be glad to hear them.
