Thank you both very much for your replies. Your answers are extremely helpful and it sounds like the newer SDHC USH-I cards are the way to go.
You also both mentioned the sped of the cards. I mostly plan to shoot skills, but maybe some limited video. Also, while most of my shots will probably be single shot, some pix may be shot using continuous. Any additional advice on the speed of the cards would be appreciated. Should I just get the 95MB/s cards to be safe?
And, finally advice on the size of cards would be helpful. Is there any image quality differences among the different sizes?
