I am about to make a purchase - can't decide if I need the Elite 
version, or if should use X-Rite Eye-One. I currently use Spyder2 on 
my older machine. My new machine runs Vista 64, will be printing to 
an Epson Stylus Pro 3800 from CS4

1.I do not need projector calibration - is that a large part of why 
the Elite package is so much more expensive than the Pro?

2.Spyder3 Pro cannot change B/W Luminance. How important is that?

 
3.I read a posoting saying that luminace calibration more important 
for LCDs - true?

4.Why should I get Spyder3 Elite instead of the X-rite Eye-One 
Dispaly 2?

I read a review that says Spyder3 Elite suffers  "Limited correction 
of luminance" compared to an LaCie Eye-One

For the price of Spyder3 Elite, I could get the X-rite Eye-one 
Display 2 calibrator - version 3.6 of the i1Match software is suposed 
to be Vista 64 compatible...


Thanks
