Best is the best. Mint Best Tracker is the easiest one I have used, sold the Feickert which is nice but just didn't need all the different options it and the others might provide. The Mint is specific to the arm/table combo, mirrored and so easy to use, after you get used to it you can align a freshly mounted cart in less than 5 minutes. Use with a good jewelers loop which is offered at time of order. Enjoy the music
