You can definitely get ABC, NBC, CBS and a whole bunch of other stuff. I am in the far west also and can get all of that with a C band (big dish) setup. If you have good sight lines to the arc (Clarke Belt), you should be able to get from in the 70s west to 139 west.
The key is to keep your investment low. Look for a big dish (solid spun aluminum first choice, small hole mesh in good condition second choice) with a little dish mounted nearby. This usually means that the owner has abandoned his big dish in favor of the expensive convenience of Dish or Directv. I have gotten two good C band big dishes this way for free. Half the time they just want to get rid of the big dish. Best to also get any old receivers, actuators, lnbs. Keep costs down.
Then post here about what you have and the good members here will get you going in the right direction.
Average cost to set up? Maybe $500, but people have done it for half that - so five to ten months and you are in the black.
When I had Dish and Directv before, I found I was watching maybe ten of the channels. With them, you learn nothing, own nothing, and pay monthly for the privilege.
Good luck!
