My director has Schirmer, but he's open to other editions.  Personally, I tend to avoid Schirmer as much as possible.  Is there any reason to use something other than the Novello/Channon edition?  It seems to be a little pricey, but has the most up-to-date scholarship.  We're doing it with organ so compatability with available orchestral materials is not a concern.

 

(Aside:  I'm surprised there isn't - as far as I can tell - a Barenreiter or Carus edition.).

Thanks!
