snap on, bahco(same owners), mac tools, spring to mind, as does expensive. @70% of my tools are Bahco and its good stuff, i'm pretty sure bahco bought snap on within the last 5 years or so and not the other way around, but a word of advice, while most snap on gear is 100% top notch, other bits can be bought identically without snap on stamped on it. Irwin/Record is another one i cant speak highly enough about for plumbing tools but for the rolls royce of plumbing, your looking for the Ridge Tool company, like snap on lifetime guarantee
(what a tool geek!!!!!!!!!!!

).
