I won’t comment on quality as that is more a personal choice but indicator style is worth considering when purchasing.
The indicator on the left is what Fox owns and is the most common general purpose style sold (2” dial face with 1” plunger travel)
The one on the right is referred to a dial TEST indicator. It is similar in cost to the first style but has far more versatility in that it can get inside pilot or dowel holes and the arm can be manipulated to see the dial face much more easily. This one has a range of .040” and I would bet in the 10 years Fox has owned his neither he nor his buddies had an application where more than .040” of dial travel was required. $117 on Amazon:
