I think adverstising should be made first of all intelligently.
It does not mean anything to post a paid advertising in a place where nobody sees it, or in a place where there are people who cannot or are not willing to do this activity.
Also, if you do not have too much money, you cannot afford to make paid adevertising.
So, this depends on your financial possibilites. I would say it depended also on your skills to make publicity (use a computer, make your own banners or speak in public about SFI etc)...
Personally I prefer to make free advertising, because it would not be interesting to notice that the results of a paid advertising are similar to the ones of a free one. However, it necessitates much more time, but on the other hand I trust more what I do for myself...
