Around here, 123s are readily available in supermarkets as camera batteries; they are just stupidly expensive. In an emergency they could well still be available after more common sizes have sold out.

I have a terribly varied set of batteries, not standardised at all, but at least I can probably find a use for any batteries I come across.
