The only other options I can think of would be the Ed8 (though many say the Sig Pro sound better) and the Beyer T5p which has a different sound signature.
And I think you overpaid by a bit which may account to the lower value ;P

Oh did I? Where would you buy them not for less than $1200 USD?

Mini-update: I've never heard Lateralus sound so good...

Where do you purchase them for 1200NZD?
