I'm looking for the best bang for the buck (who isn't?) Is PNY better than Kodak/Sandisk better than Lexar/Transcend better than HP/Kingston better than Adata???????? Or are they all the same with different names on them?! Prices vary greatly, as do the claims of the companies that make these devices. Do they all do what they say they do? I have a Canon S5 IS approx. 1.5 years old. I'm looking specifically for a minimum 8 GB class 6 for use taking video. Any suggestions? Thank you.
