Have you considered B+H? They will ship anything, anywhere. I once bought US-only NEC Spectraview software from them and had it shipped to Norway. This was the only possible way to get it, NEC did not sell it to European customers and would just redirect you if you tried.
You will have to pay customs when it arrives, but that's just calculated from the purchase value in the normal way. They don't care what it costs in the local stores (I think. You may want to check that in advance).
Yes, Dell is a well-documented rip-off. I'm frankly surprised they're still allowed to remain in business. They have disclaimers for every possible scenario. They advertise "high-end" products, and if you complain, they say "oh, it's not that high-end. This is within our specs".
Dag, you are a star! Just checked and B&H do ship monitors to NZ. Shipping is NZ$220, so even if I had to pay our GST (15%) I would still save NZ$600.
So is that HP Z30i of acceptable quality? I actually looked at Eizo, and they were another $1000. I just checked the other B&H 30" 2560x1600 displays, and the Z30i is my best option AFAICT
I never tried hp monitors. The original Dreamcolor LP2480ZX was a pretty advanced beast with RGB LED array and a native 10 bit panel specially made. Even today you won't find that anywhere. It was also the most expensive 24" commercially available monitor ever made, even Eizo was cheaper. I miss it, it was nice to have around.
I think the z30 is probably OK. They have a history to live up to. It is wide gamut though - I assume you're ready for that? You know what you have to do - get a good calibrator. Calibration software should be included or at least available extra, you really do want the ability to calibrate the unit directly, without having to do it in the video card. You still need a good sensor.
