I bought the festool metric one here in Canada. Nothing special about it. I have a stabila metric/Imperial and is a real nice wooden one, no slider and I hate combo measurements. And I have wiha plastic water proof one, Imperial, with a slider. That's my go to ruler. I had a starrett wooden one for years with a brass slider and that was great but snapped on me one day and I have a real old craftsman one with a brass slider that I don't want to break..I think I like the wiha the best.
