The currency calculator/estimator on the site is wildly inaccurate, I think it may be rigged to show a lower converted purchase price than you will actually pay, the difference between what their currency calculator shows in your countries currency and what you actually pay when converting your currency is in my case a difference of some £450 more expensive.
Its OK for buyers in the US but any person from another country I advise STAY WELL CLEAR OF IOFFER!
