Hi there masondj3,
There are two versions of the Sky+ box (well as far as I know there are not more, perhaps someone will correct me) the first, older one, in a direct comparison is not as good as the Panasonic 30 for fringe reception, however it is better than the original pace 2200.
The second Sky+ box is notably better than the first one for fringe reception, but I haven’t seen any tests of it against the Panasonic 30.
There are a couple threads in the Sky+ section that also cover fringe reception so it might be worth having a look in there, if you haven’t already.
