The original Spyder has been a mixed bag. There have been users that got "dud" units but Color Vision did replace them. A new unit (Spyder2) was just released this week, said to be much better hardware. I did beta, it was OK (slow) and the new software is nice but I still think the Optix XR and now the NEW Eye-One Dispaly2 (also announced this week) are better. Until I started testing the Eye-One Display2, I'd say the X-Rite Optix and Pro software were tops. They now take a close 2nd to Eye-One Match 3.0 (new, free upgrade) and this new Eye-One Display2.
