Hi Jeroen B,
I bumped in to the Zinwell digital products sales manager from Taiwan at the CeBIT last march and talked briefly about their scalers. I'm interested in obtaining one as soon as they have a version that scales PAL up to 720p (the native rate of my Toshiba MT7 projector), which would probably be in their newest product ('somewhere this spring'). Let me know if you need his e-mail address or if there's another way I can help.
