Great sharpness, color, flare resistance, and very compact in a rugged full metal jacket. Manual focus feel is superb and weather resistance is very good (medium rain, probably not a downpour).
Normally around $550, now on sale for $388.28 with free shipping.
I've owned the Sigma 105, the Tamron 90 and my favorite is the Pentax. Great bokeh, much smaller than the other two so it's easier to fit in my bag, and it's WR. All of these lenses are very sharp, but the build quality of the Pentax is a lot like their limited lenses - they are solid and fine examples of quality materials and engineering. In terms of size, think of the Pentax as having the thickness of a bottle of beer where as the other macro 100's are the thickness of a can of soup.
If you have a Pentax camera, you should really consider getting a lens like this - it brings out the most of your camera. And like all lenses on a Pentax DSLR, this lens will be stabilized because you have stabilization in the camera body!
Here's an album where most of the photos are with this lens:
