My favorite, Conaugher or Conager(sp?) with Sam Elliot and Katherine Ross. Just a good simple western.
Other favorites, Quigley Down Under, Monte Walsh both with Tom Selleck. Chato's Land with Charles Bronson and IIRC Clint Eastwood. There is another movie with Selleck, Elliot, and Ross in it and I think it was The Sacketts.
There was a TV series called The High Chapparel that was pretty good. The Lonesome Dove Mini Series' was good including prequel and sequels.
