My current cheapie digital caliper is getting a bit flaky on me, and my work is improving to the point where a more precise tool is reasonable. I don't mind spending money on quality, but I'm not made of the stuff, either :-). Any suggestions for a solid, repeatably accurate digital unit that won't break the bank? Figure a budget under $200, and closer to $100 would be better. Auto off would be nice, and switchable metric/imperial is a must. Don't need solar powered or computer output. Thanks, gents.
