I dont have any electric tools. Ive heard Milwauke is what everyone gravitates to. But im also open to other brands for less money. Im working on my own sedan car first. dont need to take apart a Big Mac Truck 1- M18 FUEL 18V Cordless Mid Torque 1/2 in. Impact Wrench with M12 FUEL 3/8 in Ratchet Combo Kit with Battery & Charger - $550 2- China tool compatible with milwaukee batteries - this allows me to invest in the milwauke batteires and later take the plunge on the better tools. do they change the batteries often? 3- China tool with its own battery set. I dont have $500 to throw right now..but $20 down with free return of i see its crap seems good to me? Is this a good deal? Then id have to get impact quality sockets and extension bars right?
