and pick out one that says "1-4 pc" under AA and AAA, NOT "2-4 pcs" which means in pairs. Also make sure it's a "smart" charger.
This one looks nice:

This one has a wall-wart, which is a bit of a pain sometimes, but it'll charge directly from 12V in your car too, which is convenient when on vacation:
