When you look for a new card I would lean toward one in original retail packaging .... I had decent luck on a few of mine that were loose, single cards in plastic case .... But since I did run into fake cards .... getting one in the original package is probably the safest way especially on eBay. I haven't been burned on the ones I got in the original package and there are quite a few at good prices now:http://www.ebay.com/itm/SanDisk-Extreme-32GB-Class-10-SDHC-Memory-Card-200X-Read-Write-HD-New-/280781425753?pt=Digital_Camera_Memory_Cards&hash=item415fe08c59And everything I have read seems like the only thing that has changed with the newer Extreme cards is the labeling .... says HD Video now ... but the card is the same as the other ones like I have .... still 32GB Extreme Class 10 @ 30 MBS ....
