For those whose present monitors are working well and wouldn't bother buying a new set if they didn't want 3D, it probably would be worth checking out these two websites for very good alternatives to securing 3D and they "do work".

I don't have the direct links but they are as follows:

HDFury.com/3D Fury and CurtPalme.com/3D Theater

The 3D Fury was just introduced on the market and it is a little less in cost and somewhat more versatile and advanced than the 3D Theater(been out for about a year) especially relating to the glasses which are shipping at the end of the month and in terms of adjustment capabilities, by far, the best I have seen.
