I sort of have something now. With REI gift card and sale, a Sierra Designs Tensegrity 1 FL joined my quiver of shelters for a mere $40. It has one small hoop pole at the feet but is otherwise trekking pole supported. If I hadn't had that reason to shop there, I'd likely have gone to a cottage manufacturer, probably SMD (Skyscape Scout) but I'm not certain. But I was pleased to find something like what I did at REI.
