If you cruise on down to the article post http://cheesycam.com/sandisk-extreme-rebates/, you'll catch some comments about the Transcend 32GB 400x Compact flash cards. After a wedding this past weekend shooting three cameras, I realized I needed a bit more space. I was originally going to order the Sandisk Extremes since there was an ongoing Mail In Rebate, but the prices on these Transcends were much better (without Mail In Rebate).
It took a bit of convincing through the comments section, but you guys have me convinced to work with these. I also checked out reviews over at BHPHOTOVIDEO.com and it's almost a full 5 star rating. We price matched against NewEgg, Amazon, and it turns out that BHPHOTOVIDEO.com came out with the cheapest price for these Transcend 32GB 400x Compact Flash cards. My order is in with Next Day Air, i'll test it this weekend to see how they perform. Really though, I feel quite confident after all the comments and reviews i've been reading and recieving.
