Stanley, my experience is that no tapes are accurate enough to depend on for finish work. Most are ok for most carpentry work. Many people will do what is generally referred to as "burn an inch" to avoid the clip when trying to make an "accurate" measurement. Ok if your looking for 3/16 accuracy over 6'. YMMV of course. Steel surveyors tapes are pretty good in my experience, no clip and a stretching device to pull it tight, no fine markings on most.
