Jay: Wouldn't the requirement for calibration every two weeks be dependent on the monitor? Shouldn't newer monitors hold their calibration longer?
It sounds like you're getting all set. You've made good choices. You could have done a "bit" better by building it yourself and hand selecting parts, but you're clearly more comfortable this way so that's the best way for you.
Yes, every two weeks IF you demand the utmost accuracy. I've found my 2690's drift very little, so I turn off my reminder and only calibrate every two months or right before an important job. YMMV. You'll find Spectraview II so easy to use you don't mind doing it every week..
You're stepping up more than a few levels. I suspect you're going to be very happy with your new system.
Nothing left to do now but enjoy!
