I'm replacing my D40 with a D90 for my compact body. While the D90 will be used primarily for casual snaps and travel, I do plan on using it for soccer when the light is decent. It seems that the Sandisk Extreme III 30mb/s SDHC cards are by far the fastest cards with the D90, but they seem to demand a huge price premium. I wonder whether they are overkill for my needs? I shoot raw and will usually burst 4-5 frames at a time. Does anyone have experience using lesser SDHC cards for capturing action with their D90? If so, do you have any recommendations. Thanks.
