I ended up getting this model:

It was a little more pricey than I wanted at $56, but it has 3 sensors for me to monitor outside, inside the coop, and inside the run. I monitor the run since it is covered in plastic and gets a nice greenhouse effect during the day.
The girls (3 orps and 2 silkies) keep the coop an average of 5-8 degrees warmer than outside temp. They also keep the humidity lower when wet out, and higher when dry out...not sure exactly how that works yet?!

The station is about 50 feet away from the sensors and they all work great so far.
Last night was 19'F here and they kept it at 27'F all night.
