Best Z-Wave thermostat?


I've had enough of my 2GIG CT-30 thermostat.  I could deal with the need for polling but the intermittent unresponsiveness issue has gotten on my last nerve.  
Amazon is having a Nexia 20-25% off sale with the Trane TZEMT400BB3NX included at $112.99 - 28.25 = $84.74
The 2Gig CT-100 which is not on sale retails at $83.98
Anyone with experience with either?
