Richard Sachs makes rolling art, Albert Eisentraut is the Godfather of American frame builders, Waterfords are becoming more common, but I look past that because they are so classic looking and beautifully constructed. If you decide that you are experienced enough to tell a specific builder your needs, wants, and intended use and want to talk to the person that is gonna hold the torch with those thoughts in mind, go with someone like the first two. With some others, the enjoyment of that experience doesn't come with the price. Ultimately, you have to live with and love the result. Among the builders that others have listed, it would be hard to go wrong, so whip out that card or warm up that checkbook...

You're gonna' love it.

Have fun.
