I have a Browne & Sharp dial-caliper(manual 6"), An older LEE balance scale & a REDDING balance scale w/LYMAN weight set, and a full set of LUFTKIN micrometers(if I ever need them). I agree with a couple other gentlemen on this forum, I prefer manual to digital any day(no batteries to die or replace). Good places to get the manual stuff is gunbroker.com, auctionarms.com, and of course ebay. Also "Starrett" has a full line of calipers and quality measuring equipment.
