Right now the plan is to just pull all the dry wall (save what i can for interior walls). Then seal whatever open seams there are in the 1/2" foam board they put up, run my electrical and what not, then put back in R13 fiberglass batting, and finish off with moisture resistant dry wall that is screwed into place.
I was quoted $2k for spray foam if the dry wall is down, and I would assume that any other company that can spray foam in with dry wall up would be about the same cost. I estimated that I'd have $1k into new dry wall and fiberglass batting. I think $1k savings is worth my time.
