Zig gave me the link from ebay. I got 2 including postage for under a tenner!!!. You can either use them as the outflow and put them in the tank (there is a 'strainer' fitting which you see on the adverts.) or fit them inline like Zig (and now I) have it.
The water goes through the unit where the ceramic part in the middle IS the hose. The part around the ceramic tube fills up with water when there is no CO2 and then as the gas comes in you can see the water slowly diminish. Then you have water within the tube and gas on the outer.
I got it/them from here:

If you are a 'penny pincher' then you can search worldwide and then buy the ones they advertise in Australian or Us etc and choose the cheapest due to the exchange rate.
