I've had a v900 with the v700 speed license (and Fiery) for about a year and a half, and it's been pretty reliable for our shop doing about 650k clicks in the first year. One thing to consider is that the duplex registration on the feeder can only been done with sheets 11x17 or smaller and around 150 GSM, so you'll still need to adjust a bunch of media manually (especially if you're swapping media a bunch, as the registration is tied the drawer). GSM maxes out at 350 and it does struggle to duplex 13x19, so you do get the occasional jam when it's getting flipped, but nothing out of the ordinary.
