My small telco-owned ISP NATs all of its DSL users, but you can get
your own IP on request.  They have about 5000 users and I think they
said I was the eighth to ask for a private IP.

I have to say that it took several months to realize I was behind a
NAT, and that only because "my" IP showed up in the CBL blacklist of
botted machines, and after great household excitement trying to deworm
all the laptops, I poked around in the router and noticed that the
other end of the hop to the DSLAM was numbered in 172.16. space, and
it turned out the botted machine was one of my neighbors sharing the
IP.

Based on that experience I'd say that there is some cost to putting
your consumer customers behind a NAT, but probably not as much cost
as buying IP space on the rapidly developing open market.
