That's a pretty good price. They normally go for around $300 used.
The real benefit of that lens isn't a 1/2 stop. It's the fact that it has USM focusing (and still has IS).
Other than focusing speed the 18-55 IS is about as sharp and the aperture difference really is minimal. The 18-55 IS is a lot smaller/lighter, but also not quite as well built.
