There's some
independent test info on the Global-CM site which makes good reading.
While it doesn't cover the particular dishes you mentioned, it does debunk the 76cm Winegard that everyone seems to love.
I'm sure that it being well made goes a long way to toward satisfying many users.
Just as the poor construction, and resistance to damage, go toward dissatisfying many other users of cheap dishes.
Personally, I'd look really hard for a 1m Primestar, used, for about free, and pick it up locally.
Of course, I am still looking for one, and I still don't have one.
That would be an excellent choice, and a fantastic price-performance ratio.
Between the two dishes you mentioned, I'm not going to offer my opinion, because I don't have any sold facts to support an
opinion.
Where are ya, that you think you need such a big dish ?
If you're really out in the weeds, then don't forget a top-notch LNB to go with the dish!
