A local (Northern California) printer recently tried to sell me his Iris when I took a tour of his facility, though I don't know which model he had. He's now printing with Epson and Canon and this was gathering dust in a back room. I think it even was converted to the Cone Editions ink, if I remember right.
If you are interested, let me know and I'll forward the contact info to you and you can talk to its owner.
