Received digital camera for Christmas and travelling to Bali in March and can't wait to try it out. So would it be wise to take a MMC with me, or can I get a cheap one in Bali. If so, where would be a good place to get one and how much each for a 32mb; 64mb and 128mb MMC. Also cost for a X-drive. Which MMC would be better to use a 32; 64 or 128?
