Full manual valve body, yea or nay?

So my duster is needing to go in to get some transmission work done

At this point it has a mild shift kit in the 727, but it is still regular auto

I was toying with the idea of putting a full manual in there, and wanted to know what you guys think about that idea

(I've had manual cars before, but never without a clutch)
I like manual ability, but retain the automatic part.
Full manual is more for people who wish they had a 4 spd...kiddin.
