iFixit Minnow 16 Bit Driver Kit

This is the perfect backup/spare kit if you already have something larger, and a great beginner kit otherwise. The removable end-cap of the plastic driver has storage space for 3 bits and the body has room for a few more, in case you want to ditch the case. If this is your only iFixit kit or you're buying it as a gift, I would recommend adding the aluminum driver (IF145-419-1). The plastic driver isn't *bad* but the aluminum one gives a much more premium feel and it fits perfectly into the case where the plastic driver goes. This also gives you the ability to have 2 different bits loaded and ready to go if you're working on something that uses more than one type of screw.
