My "server costs" for my personal web page are $0 as well, I forward the URL to static HTML hosted on Wuala. It gets rewritten to a long, ugly URL nowdays (previously it was just content.wuala.com/.../~LazyJones or something like that), but it works, is reasonably fault-tolerant and can be edited locally on any device I want.
The point is I could just have easily stuck with the .co.uk and kept it all completely free. To be honest I still could do it free by using a 3rd party redirection service for free, but this was a convenient way of doing it.
