Sugar DeDupit Product

We're currently going through a process of "de-duplicating" our Account records.  We're looking at Sugar Dedupit product on Sugar Outfitters, does anyone have any good/bad experiences with this plugin? 

I'm also looking for suggestions on what methodology we could put in place, outside of the Sugar Dedupit plugin, to retroactively manage duplicated records in any module (but specifically the Accounts module).
