Hi,

You may find the filter in this link also useful:

**broken link removed** (This is Freeware now, used to cost US$25)

Another good program I think is Elsie:

http://tonnesoftware.com/elsie.html

and it has Student and Professional versions ( http://tonnesoftware.com/elsiedownload.html )

Of course, there are many other filter programs (in fact too many) and individual requirements can only tell which is best for one needs. What you indicated in your mail I think the the above two softwares meet your needs.
