Production printer recommendations... moving from xerox 5000's

[incognito]

I'm looking to move from 2 xerox 5000 with bookletmakers on them. My main concerns are a booklet finisher that 3 side trims, scores with saddle stitch. We've narrowed it down to a ricoh 651 and 901 with booklet finisher but I'm hesitant as to the reliability of ricohs production printer. Konica and Canon unfortunately do not meet our requirements on the finishing end so.. if anyone has any feedback on the ricohs (pros/cons) I would really appreciate it.
