Update: I decided Id go ahead and order the Krups basket. However apparently Krups will not ship to Australia (Perth). I have called the only 3 places I can find in Perth that sell parts, all of which tell me they do not have what Im after. I even asked about the one breville machine that has non-pressurized baskets, and the lady told me that I had incorrect information.
So any advice? Ive had a look on CoffeeParts.com but am unsure of the size I would be looking at.
