Good round up review here

http://www.reghardware.com/2010/06/24/grouptest_3d_tvs_buyers_guide/

Good clear introduction.but misses some points:
1) While implied, the article doesn't explicitly state that it's not 3D at all. Only Stereoscopic. Like Viewmaster or Victorian novelties.

2) Maybe 20% of people who DO see real 3D, don't get ANY depth illusion from Stereoscopic video.

3) The Active shutter glasses may work for some people with one eye slightly weaker where the passive glasses don't..

4) Prolonged Stereoscopic video viewing will cause headache and eye strain. In reality unlike real life or real 3D displays(there are some not holographic), the image distance is actually always on the screen. The eye unconsciously tries to focus on apparently closer or further objects based on the parallax illusion. This is what causes the headaches or even nausea. The definition of "prolonged" is going to vary per person.

I recently tried 3D in Harvey Normans. The glasses are quite heavy.
