My opinion is that unless you need to shoot fast moving objects - sports, birds in flight - any card will do. I shoot portrait mostly 133 is more than adequate. A high speed card may also only do so much for you depending on your camera body. The camera may not keep up with the speed of the card. How often do you need to shoot 8fps? Can your camera's buffer keep up with that card? I say go cheap- Ridata, Kingston- you will figure out if you need a faster card. I've never had a problem with these brands and they are half the price of a Lexar or Sandisk.
Choose the right horse for the course...........and save a few bucks.
