My digital camera is a Powershot A60, it's a 2 megapixel camera with the ability to take 320x240 video with sound. It uses Compact Flash media. I'm probably just going to pick up a 256mb card (I've got a 16mb that came with the camera) and am wondering if it's worth spending the $60 for a 512mb card. Anyone bought a 256mb card and wish they had bought more?
