So after calling Radioshack, it appears that the 1089 is being discontinued. The 1032 is replacing the 1089. So, I'm going to pick up the 1032 and check that bad boy out. Plus, it has 3 great reviews. Dowside, it doesn't tell me if its wireless, though for an indoor/outdoor one would assume that you're not going to drill through a wall for a sensor. Also the 1032 keeps track of the high and low for humidity and temp!
