I have had my original phat PSP for almost three years and it is still running strong. I currently have a 2 gig Sandisk card but am considering upgrading for more storage. I am looking at both the 8 gig or 16 gig, but I was unable to find a 16 gig Sandisk card when I quickly searched on Amazon earlier. Which one is the better deal right now and where can I find it? Is there a difference between the Sandisk and the Sandisk Ultra II? And also, should I upgrade my PSP to either the newest PSP-3000 or the Slim, or is the original just fine for homebrew and PSX emulation?
