| Try looking up "DPS-475" in eBay, and you should turn up a bunch of units for a couple hundred dollars. They accept SDI, composite, and component in, and generate SDI, composite and component out. We have roughly 30 here (a regional broadcast hub) and they're pretty reliable... the most common failure is the cooling fan, and you can get a new one for about ten buck at a place like Digikey or Mouser Electronics.
