If you are only doing one action, you will be money ahead having a professional with the tools and experience do it for you and be done with it. Screwing up your fine action with a mistake is a big risk to take versus any money that might be saved doing it yourself.
I have the Forester Jig, Williams, and Sun Optics Jigs. The Forester is the best solution but the other two have their place in the market and work also if you think things through and are very careful.
