List them for $99 each shipped (still 2-3x scrap value).

You have old untested gear that no major broadcaster would touch (they need serviced reliability). There are 3rd parties who buy this stuff to support their clients if/when they need something fixed or replaced. You also have individuals who like old studio gear but won't pay much for it especially in unknown working condition. Pro gear is very expensive to fix, especially older items that are discontinued.

Craigslist is good for items not worth shipping, or very large cities where the odds are somebody might want your item. I see too many people listing old dual tape editing decks for $2000+ thinking somebody will pay that for obsolete equipment when they are lucky to get $100 for it from a collector.
