I'm going to say the same as Poet. We bought DD hers from a specialist violin maker. He sells a few types (not all made by him) and will trade in if you bought from him, so trading up to a larger size will not cost as much.
The process to choose one was amazing. We booked an appt. DD got to hear a woman in the store play a few of them. She then chose 4 to try. She had to play each one and eliminate the ones she did not like. We were able to choose the most comfortable shoulder rest and the case that she wanted and they were happy to 'pick and mix' from what was there.
She ended up choosing a second hand violin which was the same price as a new one, but was "three times as good" in quality and reputation. Having watched the whole process, we were happy for her to choose whichever she wanted. I'm sure we could have asked them to only bring out the cheaper ones, though.
It cost $450 or so for hers, which was certainly not the cheapest. I think there was one for $150 there. I am happy knowing I can trade in for the next size up.
If you're in Melbourne I can recommend the place.
