Recovering deleted files

I came across an ad for a product that claims to recover deleted files
by going into the freelist.  I have never used it, and have no idea if
it works as well as claimed; however, it _does_ seem to be a useful tool, and
was wondering if anyone out there nibbled?

Name of the product was "Buttsaver" by LoneStar Computer, and lists for
$185 US.
