Ebay is a good idea to get it cheaper, but you should ask if its really clean...When my first one was "finished" last year I looked for the same because I got used to it. At ebay I got it for less than half the price ( including shipping), but the first one looked like they had steamed the milk in it, not only empty bottles, so I sent it back. The next one was ok!
