I'm having Sky Freesat installed by an independent. I have purchased a Pace DS430N (GBP67) for my primary TV. As far as I can see it get s pretty good reviews. However, the installer will install the satellite system and supply one box for GBP200 (2 rooms). He will supply a Panasonic TU DSB30 (used) with the installation. Now my question is. The Panasonic is not exactly the latest one but is this one OK?
