I use VSS and for small projects, I've found it to do everything that is needed.  The issue with larger projects is when 2 or more people need to work on the same file, but other than that, it works just fine.

I believe there was also a visual studio client written for SVN called ahnk or ankh or some such combination of a, n, k, and h.

Seriously, if you don't need the extra features of SVN, and you are on a small team, just use VSS.
