The '''expensive''' ones are what a lot of mechanics use these days, instead of compressed air tools, being more portable, much like a battery drill, or winder, but built from the outset as Impact drivers - good ones are not cheap (£150 upwards), Hitachi, Makita, deWalt or Sealey would be good makes for instance... the lower rated ones use 1 3/8 hex drive, mainly for driving large screws, the ones you prob. want have a 1/2" sq. drive, and start a roun 180~200 N-m. Even the top ones will have a job getting a T25 wheel nut off, in fact I've broken a 2 ft powerbar getting someon'es wheel nut off so that's not saying much the way they are overtightened and left to rust.
			But something a round 200~250 N-m is useful for quite a few jobs a round the vehicle.
