What lens to get next?

[123SA]

I just got my Pentax *ist DL and sigma 18-125mm lens. I am still learning how to to take good photos with it.

I'll be using my camera to take photos of kids in action, family events, sporting events and of course my December 2006 disney trip. I am looking ahead to my next lens purchase. Any suggestions? I think I may want more zoom.

Thanks!
