Definitely expensive, but really not that hard to find, IME. The Harris Cyclery almost always seems to have them. And besides the typical US sources like Bike Friday that typically have a reserve in stock, there are a few places in Europe where you could order one if you're desperate. Moreover, you should get a decent amount of mileage out of a well maintained cassette/chain.
