Several months ago, I took some lessons at a nice club in Orlando called Metrowest. The associate pro I worked with charged $90 per hour, but that included video swing analysis on an advanced computer program. The head pro there charges about $200 per hour (he is currently Se Ri Pak's coach).
On the other hand, I am now taking lessons at a public course closer to my house. The course and driving range are nothing fancy, but the pro I'm working with only charges $50.00 per your. He does video swing analysis as well, though we view it together on his camcorder at the driving range. While the accommodations are not as spectacular, the price is much more reasonable and I think the current pro I am working with is better than the "associate" I worked with at the nicer club.
Bottom-line, more expensive does not always mean better.
