Carseat suggestions

I am writing to solicit your opinions. As I watch her little feet creep closer and closer to the edge of her infant carrier, I am beginning to think of Tori's next carseat. Can you give me your experiences and opinions on the convertible carseat that you used (or that friends may have used)? I know I have some time still and am not buying anytime soon but would like to keep my eye out for some good sales.
