You are correct about the bible belt. In North and SC we cover about 15 counties or so and one county in particular is full of duplicators especially in the rural churches. When we go and talk to them about a demo of an MFP the typically respond with something like "We have this new technology called a riso." I bet I have heard that 50 times from a church. They truly believe the duplicator is the greatest thing our industry came out with last year.
Other than that they are pretty much dead in our market.
