Monitor calibration - Which one?

[wedding photographer]

I have the monitor calibrator called Colorvision Spyder 3. I have a mac and two PCs. I have used Spyder 3 for a while and I have noticed that the colors are different on all three screens. I assume the purpose of a monitor calibrator is that the photographer sees the same colors his/her clients will see...Anyway.
I have decided to get a new calibrator. I don't want to spend a lot of money on it. My budget is 150-400.
What monitor calibrator can you recommend. I do wedding photography and I shoot a lot of Indian weddings where true colors are essential.

Thanks!

Frankly unless you step it up to a color accurate monitor, as well your calibration result wont be any better. I have a spider 3, eye one and a huey. I currently use the eye one on my 30 inch HP zr30w which is 99 percent of the adobe rgb gamut (and 30 inches). I also have a 24 inch lacie. I would seriously condsider a better screen for color accuracy rather then trying to get a different result with a similar color calibration tool. Ive had a 30 inch apple screen and when dragging images across the screen the skin tones would change. But to answer your question in my opinion the EYE one display 2 is the best calibrator on the market right now.

It could be monitor issues alone as SuperJ says. Or just in your technique using your Spyder. Or it could be different angles to your ambient light.

I have a Color Munki and really like it. It improved my printing more than anything else. And my monitor is Poo. I need a serious upgrade in that dept. I get much better color and brightness out of my prints after calibration. I am just looking at something on the screen that looks closer to what I would be printing on my printer.
