For which camera? Extreme III is faster, but your camera may not be able to take advantage of it. If you want the big card for video, even the regular blue SanDisk cards can cope.

oh sorry i didnt add enuff info.. its A570IS.

And also might plan to get Rebel XSI in summer or fall its depend on my wifes perimt LOL!

Thanks!

The Ultra II should be OK for the A570. On the XSi, who knows? There isn't a production model around yet for people to play with. But unless you machine-gun whatever you're shooting you probably wouldn't even need an Extreme III for the XSi.

Do Extremes have a durability or higher MTBF than Ultras?

Not enough to matter unless you're filing the card every day in the Antarctic or the Kalahari.

Whatever is cheapest and Sandisk. Speed hardly matters on P&S except for download from card to computer.
