20 and 20/20 collector's sets

Could someone let me know of any 20 and 20/20 collectors sets that you know of?

I need specifically blood or death necro and heal monk sets...

As a head start to the list, the 20 20/20 set for fire ele is in Droknar's Forge.

Look in the community works section for a very comprehensive (if a bit disorganized) list of collectors in the Crystal Desert and Southern Shiverpeaks.
