I bought the 1/2" drive from ToolDiscounter , really didn't need anymore 1/4" , 3 /8" ratchets--received it real fast. I been using it for two weeks and am really impressed! The chamfered edge is a nice touch--the only thing I would add if possible is knurling on the handle since we are required to wear nitrle/ latex gloves and it is a bit slippery.
