The original site was specially created for this - and I was a very good product, if you recall.
I would not use sourceafe if I had a choice. Do a search on this site for more details. He was beaten to death.
Other popular products are subversion / svn, mercurial, and git. Of course, there are other commercial products that cost money. One of them is the sponsor of this site.
EDIT
If you can choose another tool / product for one of the others, but you can do it with sourceafe.
