OV/400 Word Processing being replaced by ?

I'm interested in hearing what any one out there might be doing about
your conversion away from OV/400 Word Processing.  Being a college we do
a lot of correspondence with students so I am very heavy into the Word
Processing part of OfficeVision.  The options I see available are...
... purchase DTM/400. Looks like the easiest but also most expensive
solution (not counting payroll costs)
... convert all letter production to using MS Word with the data coming
from the AS/400. Possible, and we have done this, but it's not as clean
and precise as having the entire process performed on one platform (the
AS/400) inside one procedure.
... write our own AS/400 Letter production process. We have the basics
of this already as we got into letter writing before OV/400 or even the
old S/38 text processor but it has no word wrap, no spell checker, no
font changing.
... change to Domino. From what I know of this it does not appear to be
much different that the Word route

Is anyone looking at other solutions to this issue ?  Found any
products that could automate the Word Mail Merge process ?
