I'm going on a 3-week trip to France on Sunday, and of course one of my biggest companions throughout the duration of the trip will be my Canon PowerShot S400 Digital Elph (4MP). I currently have 2 CompactFlash memory cards...a 32MB and a 96MB, which collectively can hold around 300 pictures (I think...it's just based on my usage, but it could be more or less).
I'm planning on taking many more pictures than that (figure between 500-800), therefore I need a bigger memory card. The problem though, is I don't know what size to get! Therefore, if anyone hear is an expert in the realms of photography, I'd really appreciate your assistance in helping me pick what size/brand of card would best suit my needs in this case...thanks!
P.S. I'm currently looking at a 2GB Sandisk card, which is priced at $40 US. I'm sure it's more space than I'll ever need for this trip or in general, but it fits into my budget and I won't have to keep clearing the card everytime I run out of room...is this a good choice?
