There are a number available at a variety of prices.  Here as some at
HomeDepot and Amazon...

If you want to go through Z-Wave or Insteon, there are some decent PLM
based thermostats that interface to WiFi and internet interfaces, but I
don't think that's what your looking for.

Proviso!  In MOST cases, you're going to need add the "C" wire (power)
to your thermostat wiring bundle.  Most HVAC systems have 4 wire
thermostat wires and lack the 24VAC C wire.  If you don't have the C
wire (5 wire system) you'll need to either add it or run the system on
batteries or an external wall wart.  Some people have worked around it
on 4 wire systems but there are some questions about reliability.  I'm
fortunate in that most of my HVAC wiring is reasonably accessible and
adding that 5th wire will not be a problem for me.  Your mileage may
vary.

Regards,
Mike
