I second (or third, or ...) the All-Star. Matter of fact, if you click that link, you'll see the review I entered at UA - again assuming you like 3-2, with strikes on the thumb.
I work a lot of games where I'm expected to keep the count when on the bases, and having the notched indicator so I can "feel" the count, rather than see it means I can always know the count without having to take my eyes off the action.
