I'm after LCD versions, with good features and they must be from the same
model range for looks and be flush fittable (I expect in a standard
recessed
box).

You'll find it difficult to find flush mounted thermostats.

I would fit a programmable thermostat and not have a timer. If you must have
a timer, just stick the heating on 24/7 and use the programmable thermostat
for timing, which it can do a much better job of than a on/off programmer.
