Thanks, my ST-E2 is due to arrive tomorrow and just like Brian warned I forgot to order a battery with it. [:P]
After reading several user reviews I was concerned that they may be difficult to find.
Adorama has Kodak Max for $5.95 but even for just one4-6 day shipping is $5.00. I'm casual enough at this point I'll probably pick one up at Wal-Mart tomorrow and tack one on to my next Adorama order. (Which, hopefully, will be a pair oflight stands and umbrellas soon.)
