which one is the best sd card for this camera? how much space ( giga ) could it have ( 2,4,8,16 ) ?
<= 4 GB - if you want to start CHDK automatically (autoboot loading method) and you don't want to use the multi partiton setup / partition swapping
>= 4 GB - if you start CHDK manually (with "Firmware Update") or want to store many images on the card
