Get the Sony, the sony model is a higher quality, and more xpensiv camera, so if the rental price is the same. You could easily buy something like the Elura as it (and the TRV) is a consumer camera. Eluras are only a few hundred. What is the rental price, are these the only 2 they offer?
That being said you will not be getting a good prefessional experience with either of these cameras.
