I'm using an older Olympus D-450 Zoom--1.3 MP.
It does a remarkable job for it's age and is way more than needed for e-mailing. The real reason for this trans is to advise of Costco's EXCELLENT deal right now on Ni metal Hydride rechargeable batteries. For $25 they're selling a pkg. deal that includes a Charger, 6 AA's, 2 AAA'and I believe, 2 C's and 2 D's. My Olympus takes 4 AA's and they seem to last forever between charges and I carry 4 Alkalines for emergencies. You might want to check them out if they'd fit your camera.
