If you're looking for inexpensive living, this (or one of the other coal region towns) would probably be the place to go. Real estate is very cheap. I would not move to the area, though, if you're expecting to find gainful employment. A good paying job will probably come with a lengthy commute.
I would highly suggest coming to visit the area first, if you haven't been there yet. IMO the best bet would probably be to look at some of the area surrounding the coal towns. There is lots of beautiful countryside here, just beyond the culm heaps.
