I have seen the Meridian/Faroudja shortly.
Was projected on a reasonable big screen (2,5 metres wide) as back projection.
The picture was not easy to judge here. They played upscaled DVD which was not the best way to show such a product.

The Sony VPL-VW100 i have seen demo'd with HD and the viewing conditions were better. Since that is only 1/3 of the price it seems more attractive to me.
