CT1000 Thermostat

I see that the 2Gig CT1000 Zwave thermostat is listed as out of stock here and at several other vendor. Has it been superseded by something else? I have several and have never had a problem with them.

I still use mine as well. Demand has largely replaced it with the ADC T2000. The CT100 is still available from lots of retailers. Z-wave devices are typically very widely available.
