Agree with ChrisK1970 regarding wheel lugs.....get a 1/2" impact, many to choose from. Regarding the combo kit, I would consider the Ryobi, they have a large line and of good quality and fairly priced!. If your not concerned so much with budget and want to start off with better then look at the big four brands, Milwaukee, Makita, Dewalt or Bosh. Me personaly I like Milwaukee, between there M12 & M18 lines I have just about everything I would ever need from cordless tools.
