The Wera screwdrivers are very nice. You can get a good deal on them at Sears with points and coupon codes every now and then. The SK screwdrivers get good reviews as well, but can get a little pricey. The thing I like about Kliens is that they have the markings on the end of the handles to tell you what it is. This is very helpful if you have them in a tool bag or something similar.
I may get some flack for this but these craftsman "diamond coated" screwdrivers are not bad at all. They really get a good grip on less than perfect fasteners. you can pick a set up as a backup set for cheap with points.
