>Can anyone recommend a decent, low cost hosted source control provider?'

If you have your own Web Server you can host Subversion pretty easily on your own. For Windows VisualSvnServer works great. More info here:

Using VisualSvnServer makes the server setup much easier yet - run an install and set up your folders in the provided UI. Takes all of a few minutes.

Lots of free online hosting is available for open source projects. If you need security to prevent open access, then you have to pay. Also using GIT or HG are considerably different than CVS style source code management systems - personally I still prefer something a little more structured like SVN than the somewhat whacky push/pull mechanisms of distributed source repositories.
