As I understand the datasheet the LM358 will take a common mode input up to 28.5 V when running off a 5 V supply. Cheap and available in DIP. I was doodling a similar design myself the other day (for monitoring currents into and out of a battery bank via an Arduino) but I have other priorities than actually making such a thing for the moment.
