I picked up a couple of these cards from E-Infotech in Glenfield. They are selling them for NZD$100 each. I had seen them on B&H for about USD$34 or NZD$42. I asked The guys at E-Infotech about the huge price difference and they explained that bought them in NZ and they paid a high price for them too. They offered me a discount on my next purchase. E-Infotech has been usually around the cheapest in the NZ market but it shows that it always pays to shop around.
The cards work fine with my 5d mk2 and are still loads cheaper than the Scandisk CF cards. Stay away from the 133x as they will not allow you to record the maximum duration clips.
