Considering no Adelaide sponsor sells the Giotto I hope its ok if I mention xxx. They definitely sell the Giotto.
Although a good store I find their equipment overpriced. I would highly recommend speaking to one of the interstate sponsors such as Talk Coffee. It would be considerably cheaper to buy from them even with the delivery costs.
You could always go to Rio to have a test run of the machine then buy from one of our sponsors. It sounds cheeky I know, but we have some excellent sponsors on this site who contibute greatly to the coffee education of many so Im happy to refer people to them at any opportunity.
