the only wrench brand i have never broken was craftsman profesional, they are a fracion of the cost of snap on, mac, cornwell or matco. now i do have alot of snap on and matco wrenches too. helps if we know what kind of cars your working on though, 5.5, 7, 8, 10, 13, 15, 18, 21 is mostly what you need for GM stuff. i also like snap on's screw drivers more then the other brands. a must have is a 3/8 impact and 1/2 impact. those are a first buy, don't be cheep on those.
