   Note that there have been recent drastic reductions in prices
on photo lithium batteries, due to their increasingly common use in
things like flashlights.  You can get a CR123A sized lithium battery
for less than $2 from a number of online sources.  For instance, $1.25
from http://www.batterystation.com

Of course, they're still about $9 each from the local drugstore,
which might be a problem for a nominally "consumer" product.
