That is the one I got because of the terrible reviews of the HF one. I like it so far. I love the clear top and how large the top is. I can put larger objects in it than the kind like HF where the top is smaller than the bowl. I haven't had it long enough to fail but I was impressed that it wasn't too noisy.
As for medium, go to a pet store and get the Izzy brand desert sand lizard bedding. It is crushed walnuts. There is numerous threads on hear recommending it. I used it with some novus 3 because I already owned it. I hear the polish mentioned above might even be better but why not use what you got if it is good as well.
