The Aldi machine is great, my brother has it and it makes a great coffee.
You are stuck buying the pods that go with the particular brand machine you chose, so chose carefully!!
We dont live near an Aldi, our closest is a Coles and Woolies. So even though its not the best out there, we've got the machine from Woolies. It takes the Neslé Dulce Gusto pods sold in Coles and Woolies which taste great, but the machine has no milk frother.
We are planning to move house back to the city soon and may upgrade our pod machine for something better once we have better access to stores!
