Is there a difference between brands? There are some "OEM" (claims to be samsung memory) on the great auction site that sells for $50AU for a 4GB@150X CF Card. Whilst there are some of the RiData brand 4GB@150X for $130. I can get a total of 8GB with that price of one, and not to say about the geniune 4GB Sandisk Extreme III.
Will a 80X and 150X really does make a difference? Providing that I only shoot a couple of bursts (maybe 10 RAWs), with my D70's speed, I tested that 80X is already overkill for the camera to write, but not sure about a faster camera's performance.
I don't really want to spend over $80AU in total to be honest...
