I just got mine, had it out and played a little last week, set it up and check aim at home, you can get the 32mb card off Amazon for like 18.00
that's what I did, put the floating back door on, not much sound with it though, I have tryed r2 to r5 recording, didn't see a whole lot of difference, once you get used to the menu screen access and use, it all
falls into place, very cool...have fun
