I know that no one in this forum is much interested in vintage analog equipment, but I bet there are some old timers like me around. I'm a video artist in need of a functional DVE system with target frame store capability, to make "trails." These are typically large, heavy multi-box systems (the very definition of obsolete). I know that there must be a few that missed the trip to the dump hiding in closets and collecting dust. I'm looking for suggestions for how to find one. Ebay is a joke. Periodically a console interface box shows up, but it is useless without the rest.
