Actually, they aren't a bad deal.
Most are in fair-to-good condition (at least from the photos). Toss out the obvious one on top, figure $33 apiece for the other three portables and at just a little under $100 for the empty
porthole cabinet, that makes the remaining ones seem fairly priced.
I'm really curious what the picture-frame cabinet one is. It looks like a Dumont logo under the screen, but I can't tell without enhancing the photo.
