This is the first harp thread I've seen on Mudcat for a long time, so *wave*.
I haven't been deeply impressed by the Harpsicle models, but many people love them. And I do think you can make meaningful, accompanied, rich music on a very small harp or a harp without sharping levers. In fact, none of my harps have them.
Of course, I play wire, and nobody on this thread seems to be playing nylon/gut, but who knows: there might be somebody out there. :)
