I recommend fiber optic cable over dish all day, every day. A solid wire is always going to be a superior mode of transmitting data to a dish. Bad weather can knock out the dish communications, and this could inconvenience you greatly.
I am currently on a satellite internet connection. When it is raining - my connection dies. So I had better have already saved the hubpages work I'm doing when it starts to rain. It is annoying. Were I to have a solid wire connection rain wouldn't affect my connectivity at all.
So think about it before you commit to dish.
