With well over a decade of experience in design, prepress and digital imaging I think I can steer you in the right direction.
First and foremost, it is important to understand the fact that regardless of what monitor brand you go for or how good the monitor is, you will need to invest in a good calibration device. One device that caters for both the screen and a printer. I am assuming that you are a photography enthusiast using a DSLR and need to print some of your work on a decent photographic inkjet printer models by Epson, Canon or hp. For that purpose I would recommend that you maintain an RGB (eg. Adobe RGB) based workflow. Hence the calibration device (Spectrophotometer) that you buy will have a dual function: 1. Calibrate your monitor and 2. calibrate your printer as an RGB device. Of course, it is more cost effective to buy just a good screen calibrator (Colorimeter) in order to calibrate monitor only. You would then have to rely on color profiles that you get with the printer supplied with the printer manufacturer. This works but I must tell you that the first option or the ability to calibrate both monitor and printer provides more control and better end results.
Now, back to your original question: Apple and Lacie LCD screens, especially the latest ones are very good and can be calibrated successfully. Apple LCD screens are extremely bright and people in the graphics industry have complained about this, the idea is to wack the brightness down to half (approximately) and then calibrate the screen to suit your purpose. The idea here is to get a good close match between the screen and the printed result, know that this will never be 100% simply because screens are backlit devices and printed matter is viewed by way of reflected light. The ambient temperature (the kind of light) in your working environment has a big role to play in all of this, same applies for the type of paper you use, considering that you will stick with original inks from the printer manufacturer.
My recommendation, and this is if you can afford it, is to go for an EIZO LCD screen simply because these screens (The ColorEdge range) have been specially designed for graphics and photo professionals. have a look at this link:-

From the "Products" pull down menu on the web site, choose "Graphics Monitors"
EIZO screens are excellent, maybe you could call them and see if they have an authorised dealer in your vacinity. Go down and talk to them and get a demo.
Also, don't feel intimidated with all the technicalities of calibration, the latest generation calibration software and hardware is easy to use. With a bit of practice and trial/error you will get to learn about it pretty fast.
It would be useful to know how you shoot: JPEG / RAW ? What software do you use to process/retouch/color correct your images. What printer do you own and what kinds of papers do you print on ?
Hope that helps and saves you valuable time. If you have any further questions, don't hesitate to ask.
