So i am looking to calibrate my monitor

So yes. I am looking to calibrate my monitor. I know it needs to be done and i should have done it a while ago, but have always been daunted by the task, and had a few questions.

Is it difficult to calibrate your monitor?
What makes the calibration pieces more/less expensive
What is the best bang for the buck calibration device? (I do not have the greatest monitor yet, and am looking for a somewhat budget option)
How often do you calibrate your monitor?
Anything else i should know about this?

Thank you all very much.

Is it difficult to calibrate your monitor? no.
What makes the calibration pieces more/less expensive basic kits do one monitor, some do muliple screen setups, some can calibrate printers too I think
What is the best bang for the buck calibration device? (I do not have the greatest monitor yet, and am looking for a somewhat budget option)IMO Spyder2express (used) or Spyder3express
How often do you calibrate your monitor?you are suppose to do it monthly, I don't do it that often cause I'm lazy.
Anything else i should know about this?i do it in the dark so that no ambient lighting can effect the reading. Pretty straight forward I really like the Spyder system.

I just bought the Spyder3express. It's very simple to use and it gets good results. I would get a more sophisticated unit if I was to do it over again. Better units allow more control of the end result, better able to color match printer output.

I use an Eye One Display 2 and calibrate all of my monitors monthly.

Adobe gamma will get you in the right ballpark, & it's free. You can check the calibration a bit better in Post #6 of this thread:
