I have two XAs coming from ebay right now, and I intend to twin them in master-slave configuration and shoot stereo [3D] slides with them. For me the XAs were the easy choice vs XA-2s, because I can better control aperture and depth of field. I'm looking forward to them, they should be fun!
Several Eckerd drug stores in my town are ringing up Duracell 76S silver oxide batteries (single cell, blister-packed on a black-and-orange hanging card)at 47 cents each.
These are the cells that work so well in my Vivitar 35ES (diode-adjusted to run a 1.5 volt cell), Olympus XA/XA2/XA3/XA4, Nikon FM/EM/FG, and a few other cameras.
These batteries normally retail for up to $3.99 or more, in U.S. dollars.

IMPORTANT: there is apparently a switch in packaging. Older packs (47 cents) have four squared corners on the card. The newer cards have a rounded upper right corner, and they don't ring up at 47 cents each.
I don't know whether this is consistent at all Eckerd stores. It's worked at two in my town (Rochester, NY). I'd recommend asking the sales clerk to price scan a battery card before purchasing.
