Just got a k10d for that price, and the pentax 18 - 55 is actually quite good, and not THAT bad, it has a usable focusing ring, metal mount and a good lens hood
And the newer version of the 18-55 is better then the first version, they upgraded the resolution to work with the K20D. I have seen a few comparison shots of the two, and the new version is noticeably better.
