The camera only requires a good class 4 card...I try to get 6 or 10 but mostly to speed up data transfers to my computer.
So I will go with good branded cards that have good feedback because the last thing you want is 32GB of lost data.
A friend of mine bought a "high" speed card from Ebay and we went to a figure skating show. He was talking pictures and everything was looking fine...when he started checking them, the card was saving the last image taken only!
I tried that same card with my camcorder and it records for a while then just keeps saving the last few seconds of the clip...so make sure to not go to cheapo on the card since it is something you will relay on all the time.

No need to break the bank either of course.
