If scrolls are hard to come by, you will get a LOT of mileage out of playing a regular Cleric (or Cloistered Cleric).DMM was mostly to be able to quicken a buff in the first round (and perhaps another buff in the second round if I eventually took 'extra turning')... not for the normal persitent metamagic cheese which is perhaps too cheesy and broken.
As far as the spell compendium goes, I might have issues getting spells off of that. As you know, the archivist only gets a couple of new spells each level. If scrolls are as hard to come by as I think (either in treasure or from shops), do you think that SC might not be as great a choice?
Alternately, consider talking to the the other Cleric, and asking him to take the Scribe Scroll feat. Work together as a party, do great things.
