I'm about to be a new mom and need a small digital camera that takes very fast shots so I don't miss all those cute baby moments. I'm not as concerned about quickness between shots as I am about the shuttter speed when I push the button. I want virtually no delay. Any suggestions? I want something small to keep in the diaper bag. Something under or around $300. Thanks!
