3D monitors

Iv been thinking bout buying a 3D Monitor for my pc Im looking for a quite cheap one maybe bout £250 or just things to look out for while choosing one as I dont know much about them and I have a GTX560Ti

Do you have an Nvidia GPU? If not it will be a waste as the AMD solution requires third party software and it's not as great the Nvidia solution. I just want to ask before I start scouring the interwebz for a monitor. :P

Don't bother if you're going cheap, backlight issues are everywhere in cheap 3D monitors.
