I currently have a kodak 4mp, and am thinking about upgrading.
I recently saw a kodak 7mp model c743, on their website, for about $200. I then saw it at circuit city for $170. It looks like a pretty good camera for the money.
I loved the kodak software, so that is why I am trying to stay with them.
I do not recommend getting anything with a large zoom. I have one right now with a 10x zoom and unless you have a tripod in your back pocket to use, the photos come out blurry.
