Sorry, I might be repeating things here but I haven't had time to read all the responses. A retro fit is worth it. It will maximize your comfort on your current bike but the other important thing is that the fitter will be able to give you very good feedback about what you should be looking for in your next bike when you can get another. So be sure to ask about ideal top tube length/reach for you so you have that information to help you shop in the future.
