Hi, not been on for a while. I'm looking at buying a zgemma for upstairs as my f5s has finally died. I'm looking at the h2s but what the difference between that and the h5 or the others? I suppose if it's for upstairs it doesn't really need to be a twin tuner as I have a Vu duo down stairs. Are they fairly similar to set up as a Vu duo? What would you recommend? Thanks.
