For anyone still looking & thinking of buying, I think the RISA solid/stick or RISA Uke'Ellie would be good candidates.
I like the design of the Uke'Ellie, it's kind of like a hybrid of a Flea (from Magic Fluke Company/MFC)) and a RISA solid/stick.
Never played one though, hope to one day.
I've got a few instruments from MFC that I am very happy with, but for a travel/silent/hotel-room uke, I'd probably want to get a RISA solid/stick tenor.
