Choosing a dial bore gauge

What did you end up buying? Im looking at buying one, Fowler seems like the best bang for the buck. I was wondering if i can check valve spring height, piston to valve clearance, set up a ring gear and dial in a cam with just a good gauge and base?
You really need a dial bore gauge up to the largest bore size for mains, rods, bearings and cylinders. Micrometers for all the same, a mag base/dial indicator setup and a valve spring height mic to cover all the tasks you’ve listed.
