I prefer passive 3ds too and as far as I know the manufacturers offering this type of 3d are Vizio, Panasonic and LG. Vizio is the cheapest among the three but I found too much negative feedback about it. As for Pansonic, their plasmas are really great and they started offering passive 3d earlier this year so they don't have various models for passive 3d yet. As for lg, I chose it not just because it has passive 3d. I also considered other aspects like, quality, affordability and usability.
