Hello CAOSLC, Not knowing what you mean by "quality prints", I've been printing on the 23C with XPan negatives and obtaining "museum quaility" prints.
Other options irrespective of cost in addition to the one noted above:
-Glass negative carrier (film flatness!)
-Use a 6x7 negative carrier and cut a mask using XPan neg. as template (this is this option I use). I used a thin piece of cardboard fitted to the registration pins on the carrier. you can also use black tape, but that can leave adhesive residue.
Regards
