I purchased a few screw drivers from Sears over a year ago and they are not really the jewler's type. They are their precision ones, which gives some of them longer shafts (very helpful in opening up other computers, or pulling parts 😀 ). You won't need anything larger then a no. 1 or no. 2 philips screwdriver, and about the same in flat head. You might want to pick up some torx head drivers though (from t6 to t9 or t10 if you can). There are more then a few screws inside the new Mac's (laptops mostly) that use those. Again, Sears is a good source for them. Yes, they might cost a few dollars more, but it they EVER break, they replace them, no questions asked.
