I have Starrett, brown and sharp, and mitutoyo mics. The old Starrett 436 is the easiest to read. I paid less than $20 for it. I prefer the satin chrome finish. Favorite mc of all if the mitutoyo digital. For $125 or so, I wouldnt buy anything else new.
Fowler buy tools from other firms and put their name or packaging on them. Some fowler is chinese and can't be recommended. Some fowler is Swiss and among the best. You need to know what you are buying from Fowler.
As to accuracy, mics require careful technique. Smooth operation and well thought out controls, clutches etc help. I think even the Chinese mics will do the job. I recommend you pick up a couple used gage blocks and practice measuring them.
