Here's a link to a smart, compact, international charger:
Sony Cycle Energy BCG34HLD2RN
It is not as sophisticated as the LaCross (no full discharge, IIRC, for example), but it will charge any combination of AA/AAA batts, even or odd numbers.
I bought this for my father last October for $11.29+FS from DependableResource via Amazon, together with a pack of eneloops. Note that the included batteries are low-capacity, non-LSD. If you wait, some good deal on that may return.
