I have been using an old cordless drill with a good clutch and the tips from the $6 dynamite wrenches and just throw away the red aluminum handles.
You also have a drill whenever you need one.
I have a small 12v cordless drill that is 10yrs old and works awesome, with the clucth at its lighest setting you will never strip a screw.
I have Built and maintained all of my cars with this setup and it works well.
