I have a big ratcheting screwdriver with the drivers stored in the handle, its so nice. And for smaller stuff I have a ratcheting right angle one that's great for leverage. That plus a tiny screwdriver with 30 different tiny bits for all different kinds of electronics, and a simple drill. It can all be had for under $50, compared to removing the frustration of not having the right bit plus the right tool which is priceless.
