Spin Doctor stuff is fine, put in dozens of BBs with their tools and countless cassette swaps. If you use tools to make a living I'd get the best. Used to work as an auto mechanic and always treid to get my hands on Snap-On stuff. Even Craftsman stuff was considered second tier. But for the home mechanic and part time bike builder most any decent quality stuff will work. Do kick in the cash for a good torque wrench though.
