Dito with Onlsow - and in checking out monitors, make sure the one you eventually buy has an 800:1 or higher contrast ratio. Then it will have a higher color gamut display than CMYK print so it's accurate for color correction.

Also, buy yourself (if you're really serious about your color correction) ANY version of monitor color balance hardware/software (software package with a hardware piece you set on the screen to "read" the colors presented) to calibrate your monitor. While it's only a starting point (every printer is different, and will have different hues and such), you'll at least have the starting point.

Good luck-
