I have a $60 no name generic z-wave thermostat that when paired to my Wink Hub (could be any z-wave compatible hub though) I get nearly all of the functionality of Nest with none of the headaches. It runs on a schedule I define instead of some magical algorithm, I can get all the alerts I want in a unified interface (the Wink app on my phone), and I can monitor the temp in my house or turn it on/off remotely when I leave for vacation. More importantly, it's never not worked for any reason.
