I have a few of the Sandisk Ultra II 2GB SD version. I prefer them over the Extreme III Compact flash because the in-camera write speed is a tap faster. Although it's slightly slower in between PC transfer but that’s not what i got it for. Now sounds about the right time for an upgrade. Sandisk has announced two new up-sized versions of the Ultra II SDHC and Ultra II SDHC plus to 32GB and 8GB with 50 percents faster than last version.
