They're who I bought my Milwaukee stuff from, back when they had the deal of buy a set and get a bare tool for free. They shipped my order in a timely manner and it arrived in a timely manner, and I got everything I paid for, so I don't have any complaints about them and would feel safe ordering from them again, which I will do, once they get a better deal going and I figure out what else I need.
As far as the 70-in lbs goes, I doubt you'll notice. My 12v Fuel drill far outstrips my old Ryobi 18v, and at something like half the size and weight. For basic stuff around the house, and nothing super in depth on a car, the M12 line is awesome and there's no need for the 18v stuff. I'd only go 18v for the super in depth stuff, or if you're a pro.
