Just as an option to svn, which is starting to show it's age, you might want to look at git. You can get a free repo at github.com (or, if you insist on svn, free repos are available at assembla.com).

git is a little scary at first, but once you learn it, it is MUCH easier to manage a repo with it than svn.

Anyway, to check out git: http://github.com and http://code.google.com/p/msysgit/ for the windows client.

if you REALLY want to use svn, http://assembla.com has free repos available, and will walk you through the setup process.
