Anyone. Thanks.
For a general purpose tool (extreme accuracy not necessary), I'd go with a vernier. Get ready to part with about 150 bucks and search for Mitutoyos on Amazon. I've never needed anything beyond that. What you do NOT want to do is skimp on a precision measuring tool; if you have to spend significantly less than that figure, do your homework.
Odd, I bought a new Mitsutoyo vernier caliper 0-6" about 8 years ago and I recall it being cheaper than dial or electronic, and they hold up to more abuse than dial. Not Master verniers those do cost more than you would think.

Some of them appear to have a thumb wheel like a dial caliper has; I'm thinking that would be nice.
Those would be the Starrett master series or equal. You can still find the 123-14 like I have for roughly $200 used on the bay and they are just as good as the new 123Z series they have now.
Upon closer examination, it appears that they do have a thumb wheel, but it's for fine adjustment, not course adjustment like with a dial caliper.
