I too have the European Spectraview Reference 2690, as well as a (non-NEC) i1D2. I had such problems getting neutrality with my display that I invested in a Spyder 3. That didn't work - gave me a green hue, especially in darker tones. When I contacted the BasICColor people in Germany they told me that is exactly what they would expect using that combination of colorimeter and display. Riiiight ....
After further tweaks and experimenting, I am now getting acceptable results with the i1D2. At least, the profiles validate superbly and colours are good. The important thing is my screen-to-print match is absolutely spot on.
So in a nutshell, the i1D2 works, the Spyder 3 doesn't. YMMV.
