Kenny,
Montana is a REALLY big state so it depends on what part you are talking about. Eastern Montana is totally different from western Montana. A lot of the state is vast prairie, other parts are huge wheat fields, beautiful lakes and streams in other parts, still others have great mountain ranges and beautiful forests.
A lot of the "beautiful people":-laf (read Ted Turner, Tom Brokaw, David Letterman, et-al) have bought land there and have run up prices significantly. If I were you I'd rent a house or condo and get a feel for the area your thinking about before laying out the price of a purchase when you might be better suited for another area.
It is an awesome state. They don't call it the "Big Sky Country" for nothing!
