I wouldn't let them move her. They put a whole hand up your doodah and another one pushes right into your stomach to move the baby around.

My babies back to back and if worse comes to worse she'll have to be a ceserean, no matter how scared I am of being cut open, the pain of turning them must be alot worse. My midwife opted for a ceserean because she had a diagnosed breech. If a midwife isn't going to do it, neither am I.
Then again, it's personal choice. Depends completely on what you want to do. How far are you? Does she still have time to turn? Some babies turn right at the last minute.
