WinPure .. List Cleaner .. Opinions/Recommendations?

Anyone here tried ListCleaner by a company called WinPure
http://www.winpure.co.uk/lists  (a data deduping software) in
comparison to other products that may be out there?  Looks like some
companies like Hewlett Packard use this.

I am looking for a good (and inexpensive) datacleansing tool to dedupe
and standardise lists, happy to extract the data from database and
re-import it (which seems WinPure does) before incorporating it into
other BI tools.  Tried MatchIt from help it systems but it is a bit
cumbersome.

Particularly interested in a tool with a good phonetic matching
engine, that handles multiple lists.

Mostly work with oracle, sql and access. 
Recommendations appreciatated.
