I actually was able to buy it direct from NEC here in Sydney as a favour, after a few stuff ups with dealer I was referred to. The price (as far as I could tell, there not being any WUXi2s in any of the dealers I checked) was excellent - under $1800.00. Delivered. :-)
I spoke further with the head NEC guy this morning and (if I understood him correctly, I'm not quite sure we were both talking exactly on the same wavelength) he said the Euro/Oz versions of the monitors were literally hand picked perfect versions (50% reject rate) and had the "monitor heads" modified (not sure I understood what that actually meant) so as to be better, together with the BasICColor software, than the Spectraview II equipped US monitors. In the end, given that BasICColor is what is supported in this country, that is what I'll go with I think. BasICColor Display 4 will cost about $245.00.
AU$1800 is a very good. I guess this is the 2690WUXi1. In addition you need to buy the BasICColor software. You have to check that this monitor can be hardware calibrated. Here in Europe non of the 2690WUXi monitors can be hardware calibrated due to firmware limitations. You have to buy the SpectraView version for this.
If you can't hardware calibrate the monitor (non SpectraView version), you can use the GretagMacBeth software that came with your i1 Display 2 puck as well as the BasICColor software. No difference between them when you do video card calibration. You save the cost of the BasICColor software.
Remember that the "hand picked perfect versions" your dealer refers to is the SpectraView version, not the 2690WUXi.
I think you have to check if you also have two different versions of this monitor in Australia as there is here in Europe. The cost for the full SpectraView version including the BasICColor software and hood ("monitor heads"?) is actually lower than if these parts are bought separately. This is the only combination that gives hardware calibration of the 2690 here in Europe.
