I think i've decided on the 717 (found it for $540), now what items are a must have? Obviously memory, memory card reader and tripod but anything else? Also, suggestions for memory? Does it matter if i stick to sony brand sticks? I've found sony 256mb for $79, sony 512mb for $200, and sony usb reader for $40. Can i at least go cheapo on the usb reader? Can anyone tell me on average, how much normal resolution pictures take up (i've heard around 2.5mb) Thanks, and if anyone knows any places cheaper, i'm all ears. And if by all means, you want to persuade me to get the nikon cp 5700, go ahead and try, i've been contemplating between the two of these but chose the sony because i think i'd like to do night shots more.
