stanley 30 foot powerlock at work. 25 footer in the shop. they last a very long time unless you drop them in the lake, which is an occupational hazard when you work over water. easy to read and measure consistantly. what i do not like are the newer style and cheaper stanley. the ones that only have 7 foot holdout do not last, but they are what i buy my crew because they are prone to dropping them before they wear out! also hate the little flange on the the top side of the hook on the new ones that catch your thumb when you retract the tape. ouch. never near a grinder when that happens, either...
