Rolands may not suit because your daughter would also need speakers for their stage piano range. A furniture piano would be too big, wouldn't it? The Privia range from Casio has gotten a bit of a push recently but I have not personal experience of these, specifically the PX-720 or the PX-800. You could also try the Kawai ES6 Portable Piano if you can get one to try of course. They are very rare in music shops in my part of the world! the more compact CL35 from Kawai has a charming studio grand voice and may also be worth a try. I'd recommend you try those out for yourself and decide, as you should with any instrument I've mentioned here.
Pricewise, the Casios I mentioned would be roughly the same price as the Yamaha P140 (give or take a few pounds) whereas the P-85 is just over half of the cost.
Hopefully this will get you started in your search.
