Toyota, any parts shop, eBay.

Burson, Repco, Autobarn, Bosch etc etc etc

the OEM part appears to be quite expensive, I will see if I can find out from someone I know where they sourced theirs.

4EFE EFI Carina/Corolla and probably 7AFE EFI o2 sensors are compatible too, 4 wires and even the same connector plug as well!
Check scrapyard

heres what ToyoDIY has for the part number:

13505-16021

it only shows this number being used for 4age models though, that's not to say that others are not compatiable, just beware

Aftermarket units aka Universal 4 pin connectors the heaters tend to be a little weak in them. Some people earth the heater circuit permanently so it is effectively always on with ignition.

Its quite easy to depin / repin the sensors.
