B&H Have the X-Rite iOne Display 2 calibrator with software for $380 I think. That's a good start.
If you need a monitor and you need an LCD screen there's research to be done and considerations to be made. Photo editing is best done on inplane switching screens (IPS). These are by far the most expensive of any LCDs, but are necessary since they retain colour uniformity regardless of viewing angle. S-PVA screens may, and I say may with a lot of caution, only just suit your needs for colour accuracy. Twisted nematic (TN) panels should be avoided at all costs. These are great for games feature excellent input lag are cheap but horrid for colour reproduction. Most can't even display the a smooth sRGB gamut because of lack of 8bit colour. If a screen is advertised with a sub 10ms lag it's most likely TN so avoid it.
Now monitor for closest colour for print is probably the NEC SpectraView series of screens specifically the NEC LCD2180WG-LED-SV. But these naturally come at a price (21" @ $3500). The IPS screens mentioned above (Eizo Colour Edge, and I think the Samsung MAY be too) are a good too and cost considerably less. The other option is go for the non-LED spectraview series of screens. I use the NEC LCD2690WUXi SV 26" screen for $1400. Both of these NEC screens come with a iOne Display 2 colorimeter for calibration and feature internal lookup tables so your calibrated colour actually gets uploaded into the display and doesn't just play with your graphic cards gamma curve.
The other main consideration is colour management. Both NEC displays I just mentioned are Wide Gamut displays, even the cheaper one displays 97% of the Adobe RGB gamut which is a pain in the arse when you're looking for colour managed software.
Other options (and I am still recomending NEC here because Eizo have been mentioned already): NEC MultiSync series of screens should all be IPS screens. The LCD2490WUXi is similar to the larger and more colourful brothers in feature wise but displays the sRGB gamut for better compatibility and less colour headaches. It still features internal lookup tables, backlight compensation etc etc.
