Either of those cameras are a good choice.
Another is the Fujifilm S1500.
I am going to be spending the next few months in the Amazon Jungle. I will only have access to electricity every 2 weeks, so I need a good digital camera that uses AA batteries, preferably for under $200 but I can spend a little more if necessary. The only 2 that I have found which seem to be good are the Kodak Z 915 and Canon A1100. Any suggestions on these two or others? Thanks!
