Sandisk has 2 "brands".

The Sandisk "cheap" brand which is like having a Yugo.
And the Sandisk Ultra/Extreme series, which seems to be of better quality.

I personally prefer Lexar based on camera experience.

Kingston, Patriot and Corsair are all big names in the PC memory industry. In theory, they should all be fine as well.
