If you want to buy Trude then buy it. I have spent a LOT of time choosing a projector. I really wanted it to be a universal 2D and 3D projector but after watching some Sharp XV-Z30000 I realized contrast and colors in 2D simply meant much more to me than 3D and went for HC5 (and I don't regret it). But I didn't want to dismiss 3D either. So I chose my 3D options carefully. I've read everything I could find on Trude (some German reviews and forums). Also I've read everything on MonsterVision. Those were my two options. And I chose the latter because:
a) There were reports of better performance than standard IR emitter and glasses. As were for Trude though;
b) RF is better than IR;
c) MonsterVision 3D glasses looked nice with big lenses;
d) There were some nice deals on eBay.
And these are comfortable glasses. And it can be tweaked via transmitter or computer software. You will
see improvements compared to standard settings
by reducing duty cycle (less brightness) and delay timings. And while some parts of the image (which you looked at while tweaking) will be quite nice, other parts of the image (lower or upper part) will look horrible (much like the pattern image I posted above). You can expect the same performance with IR glasses. If you don't believe me maybe you'll believe Zombie? http://www.avsforum.com/t/1434826/sony-hw50-benq-w7000-epson-5020-jvc-rs55-jvc-rs-46-jvc-rs4810-jvc-rs56-mini-shootout-2012-2013/4350#post_23457973
And you might expect the same performance with Trude. Now, this is only my opinion based on arguments I've stated.
I understand that I might get some negative reaction due to stating my opinion in black&white. But I spent some good year reading forums filled mostly with "gray" and politically correct opinions. Once I got a projector and saw it myself it became all clear to me, where's black and where's white. I've had a plasma of the first generation of 3D plasmas (2010) for 2.5 years and I found 3D on it more pleasing than on HC5. But by all means buy Trude and tell us your findings. I might be wrong.
