I've been using SanDisk CF cards since 2002 and have never had any problems with them. Last year I started swapping out my slower 8GB cards for 16GB Extreme cards. Then I bought two tickets for an average price of about $90. Yesterday I saw that they cost less than $75 so I loosened my wallet a bit to buy another one. I shoot in RAW with my Nikon D700 and all files are around 25MB. I like not changing cards too often. If you're looking for a solid memory card, this card probably won't disappoint. I would recommend a USB 3.0 card reader as USB 2.0 transfers files almost unbearably slowly. Update November 2011: The price of these cards has dropped to around $50. I can record about 15 NEF files at a time and don't have to wait for the files to be written to the card. The speed of 60 Mb/s suits me perfectly, and it makes no sense for me to buy faster and twice the price Extreme Pro cards. Well, at least not yet.
