If you are already setup for true FTA and have a large enough dish and motor, then an OpenBox S9 or Manhattan RS 1933 would a couple of good choices. they will both receive HD and SD channels as long as you are aimed at the proper satellites and are pretty reasonable in price. There are others of course, just depends on your budget.
There is no need to pay for service with true FTA.
Please be sure to read the forum rules as we don't discuss or condone satellite hacking.
