Hi Jill. Welcome to the group. I've no experience with recunbent trikes, but I do have a recumbent 2 wheeler.
It might be helpful to know what you consider moderately priced. Recumbents are, by nature, priced higher than conventional bikes thanks to economies of scale, but there are some that are not too outrageously priced.
Be aware, however that cheap almost always translates as heavy.
Good luck in your search.
