I have the F-1 and am going yo upgrade to the Beta Master. Which ever one you get, get the Master because that gives you the controls back on the bench where you want them.
The Beta allows you to save up to 60 shots and to retrieve them later for analysis. It's worth the few extra dollars over the F-1.
