I know you used the emagin Z800.
I had the Vuzix VR920, I couldn't read text with it. Just didn't consider it worthwhile, I never tried the emagin as it was like 1500 bucks.
I suppose I should say we are getting closer to affordable VR technology that doesn't suck.
I think the Sony HMZ-T1 looks pretty ok. 720p is pretty close to good enough IMO, though obviously more is better. One of my squaddies has one, says the eyepieces are a bit close together so if you've got widely spaced eyes I'd suggest to try before you buy.
Still, for $600 or so it's not a bad thing. I doubt I'd use the 3D with AH as my squaddie said it was less than great. No head tracking either.
