Kitchenaid still sells the ravioli maker on Amazon...but it's sooo pricey. $400??
One other available product is Antree. It's got the pasta roller and the ravioli attachment, and it seems like a reasonable price for such a complicated product. The Marcato has just the ravioli attachment and is $57, definitely a steal compared to the official Kitchenaid attachment. If she doesn't have the pasta roller, I'd say to get the Antree. If she doesn't care for pasta at all, just go for the Marcato. Otherwise, there doesn't seem to be any competition on Amazon.
