The ScanDisk 63 GB  SDXC card is a geat value and I get HOURS of recording HD video with wonderful results. I prefer ScanDisk because they are reliable.  Setting up a video shoot with a client, spending hours recording and then calling my client to explain that I bought a cheap, unreliable card that failed... and NOW I have to reschedule a re-shootand the project will have a late delivery...  JUST ISN'T SMART.  I must have reliability and ScanDisk delivers!
