My 1/2" and 3/4" are Klein/Benfield. My 1" is an old, old Appleton that I bought off of a retired EC who bought it off of an old sparky in the 50s. My 1-1/4" is a Greenlee I bought off Ebay for $35.00. It looks new. I've used it several times in the 3 years I've owned it. A fellow sparky I know has benders with the levels in them. He doesn't use that feature much since a level concrete floor is rare.
