It's a shame the theft of the Alex and the Giotto happened at a place where these cool people like Simon, Jono, Kaya and Maddie work.
Apart from those two, was anything else taken like accessories, beans, grinders, other machinery etc?
I can help by looking at Ebay, the Gumtree website, the local Quokka newspaper and the Sunday times. I don't know if there's any other sites or media that the machines can be advertised.
Am sure if there's any WA snobs here that can tell us where else they may turn up, then drop a line here.
