Well I've been reading Mac and Apple related stuff basically daily since the iPhone came out, and have never even heard of these guys.
Alas, I had to get rid of my SE/30, my Classic, and my LC II. And not having bought a IIfx still stings.
Also, a modern LCDs although conceptually multisync does not actually like frequencies that aren't PC standard S/VGA. Or it was the sync-on-green causing problems.
