I played on a kohler and Campbell when I was looking for a grand. It felt like it needed lots of regulating in terms of action and tone, (it may have just been this particular piano) but I think it could be fine..
Just be careful- the cheaper the grand, the shottier the workmanship, the BETTER your technician should be to assess the quality.
Dont stop considering it- I agree with Dinosaur Tales that there are huge benefits to playing on Grands instead of uprights, but I disagree when I say smaller grands are not inferior (I have also played on a pramberger - a little stiff, but still good). Just so long as the piano is longer than 5', it should serve well. Besides, for a small room, you dont want a big piano anyway because it will be too loud.
If I were you, I would sit my daughter down at the kohler and campbell and make her play. If she has any complaints whatsoever, that's the end of it and it's time to move on to the next choice..
by the way, your link doesnt work.
