Zoe,
My thermostats were purchased about 10 years ago from a USA company called Helix Controls. At the time they were the ultimate thermostats you could by off the shelf. I believe I paid around $400Aust for them back then, but they have truely paid for themselves in light bulb and electicity savings.
You can now buy a similar Thermostat that is imported from England. They are called Habistat Proportionals with the photo cell attachment. I believe the Reptile Barn here in Sydney was selling them for around $170ea. Great price for a quality item.
