I agree with Anole... Even the larger subscription service dishes such as the DTV International and the Dish Network Superdish really aren't worth a lot of money. They are not as capable as a 36" dish, and if I were to spend $50, I'd spend the extra $30-$40 on a real FTA dish that will get you the weaker transponders.

Another thing to consider is that the subscription dishes are rather easy to find for free. Just yesterday, I dragged a DTV Slimline (the new DTV dish used for Ka-Band) out of a dumpster. It was complete with monopole and J-pole mounts, and with a simple modification and replacement of the LNBF stack, it can be used for FTA as effectively as the International and the Superdish. Discarded Slimlines are everywhere these days.
