The Pentax 28-200 was made by Tamron. But Tamron's super zoom went through several generations of development after the Pentax version came out. The most recent is apparently the best, as I recall from some reading. You might also look at the Tokina 24-200, which I think tested pretty well for this class.
You might want to look up the reviews of these done by Popular Photography. Ignore the text (which is rarely critical), and concentrate on the SQF numbers at the f-stops and size of enlargement you will use. Don't accept ratings below A -- you will see weakness otherwise. Tokina's lenses are not well coated, but I have rarely had a flare problem with the two I have owned. I don't know whether Tamron is better in this regard.
