18-55 DAL Alternatives?

Okay I really like my new K-x, but the 18-55 DAL kit lens... not so much. It's okay, but I've been spoiled by my Olympus 14-42 which is a whole different grade of lens. The 18-55 often looks soft, even when the K-x AF worked perfectly.

I would like to approach the edge sharpness of the Zuiko without spending a load of cash for the Pentax.

I was looking at the 18-55 AL II.

Any other ideas?

Thanks,

Scott
