Since you have a Canon 30D, I assume you are looking for a point-and-shoot camera.
The Canon S100 is what most DSLR owners pick for their walk-around camera.

which Canon is best for shooting children. Looking for exceptional print quality, HD video. Camera has to be fast. Not interested in changing lenses just getting an amazing shot quickly with great results. I have a Canon 30D I save for special occasions but for day to day I'm not clear which unit would work for above requirements.
