Here's a great deal on the Sandisk 64GB SDXC media going on today. This makes it even cheaper than what Transcend has to offer. Definitely a good buy for those who need the 64GB space or SDXC file format. (click here to compare some prices on SDXC via B&H).
Remember that all the new cameras are starting to move towards the SDXC format including the new 5D Mark III, and it's way cheaper than getting compact flash media (as seen here). SDXC is backwards compatible so it will work on your cameras and portable recorders that are using 'SDHC' today.
The same 64GB in Compact Flash will run you a minimum of $140 dollars +, and with SDXC it will run you just under $49 bucks (today), which is almost three times cheaper. I've been successfully using SDHC and SDXC media in my 5D Mark III for several hours of video, so I highly recommend investing in SDHC or SDXC if your cameras can take it.
