I was looking for this machine and found a good deal on ebay.
electroniccityinc 99.1% has the Breville BES870 The Barista Express Coffee Machine on sale for $450, shipping is free.
the offer says 870 instead of 870xl but I did not find a non XL version so this should be the Xl version.
Correct me if I am wrong.
