Hi, this is my first time on the boards so apologies if this is already answered. Anyway... I just bought my SuperCard DS-One V3 from DX and I am looking around for a Micro SD card to use. I had read somewhere that class 2 and 4 cards were useless on it and if used they caused hang-ups and lower compatibility than the R4, which I also have. I live in the UK and it seems finding a card with at least 4gb of storage and that is Class 6 is nigh on impossible. Can someone help me?
