Camera Advice Needed

My digital camera bit the dust. I'm not sure what happened to it. It still works, but the shutter won't open so I'm not able to take pictures. So, I guess that means that I should probably get a new one since I haven't been able to take any pictures of my little Bubba for quite some time now. Does anyone have any thoughts one what a good one might be? I'd like to stay with a Sony since that's what I have now and I'd like to avoid having to purchase more memory cards and all that. Any thoughts?? Thanks!!!
