I don't have one but am looking and reading as you. I would like one that will take lugs off my F350 and pinion nut as I can't do this after my accident. It also needs to be spark free do to oxygen I'm on so that means Brushless. There are a couple out now you can look at. There is the Milwaukee Fuel, Makita and I think I'd seen the Bosch 2pk at Menards but could be wrong. The Milky has a 5yr warranty on tool and 3yr battery warranty which may sway you. The highest torque is the IR, after that maybe Festool? So you just need to narrow it down. I would choose Milky, they have a better warranty, batteries will work on their tool line, Local stores carry it, and I like they have a 110vac/12vdc charger for the car. That will make it nice when you drive and get a flat, the lugs wouldn't have a chance. So you can charge them when needed, that's a plus in my book. Maybe a thread giving all the specs would help you and others?
