For nova style mag bases I've had good luck with CDCO on those. They are the hydraulic pivot type. One knob controls all movements. I have one for a collet for mill. They have different styles and mag ratings. I believe you can pick up a mag base and test indicator .0005 for like thirty bucks. I have several of their indicators and they work pretty good. I've compared reading with my mitutoyo's and their spot on. From what I can tell. And yes you don't need a tenths indicator but how will you ever improve or even know if you don't try. I personally have fun chasing tenths. It's a challenge and rewarding when you accomplish it. It will only make you better.
