I'd say this one has excellent image quality especially at around 24mm. Considering its price, it's an amazing deal for such an IS-general purpose zoom. It is light-weighted. And IS really makes a difference .reviewed March 26th, 2009 (purchased for $150)
The major thing is it has a small aperture, F3.5@18,F5.6@55. So it's great for landscape but not for portrait. Concerning the build quality the focus ring really is not very easy to use.
