Just about to invest in a new 16GB Card. So have two cards to sell. One is a 4GB Official Sony Pro Duo. The other card is a sandisk (blue colour) 8GB Card. Both work fine in my psp slim with custom firmware. Neither are fake cards.
£15 for the 4GB Sony Card
£30 for the 8GB Sandisk
Will post pics later if there is interest in these cards
4GB Sold subject to Payment. 8GB now being listed with my PSP Slim
