Something like this will work:

class ModelSelect(Select):
    def __init__(self, model_id):
        self.model_id=model_id
    def accept_model(self, model):
        if model.get_id()==self.model_id:
            return 1
        else:
            return 0

# Select model 0 for output
ms0=ModelSelect(0)

io=PDBIO()
io.set_structure(structure)
io.save("out.pdb", select=ms0)

Cheers,
