We are in the market for a wide format printer to add to our existing Durst UV hybrid flatbed. We will be printing on Avery MPI2923 vinyl pretty much exclusively. I've read the forums about some issues with the Roland XR feeding material for about 30' and getting head strikes but also realize there is no such thing as a perfect printer. The Seiko on the other hand, you don't find much info on them. I've talked to a few Seiko users and they all seem to love them. I'm leaning in that direction but wanted more opinions if there are any M-64s users out there. They have a $3000 rebate on the printer now and am tempted to pull the trigger. No matter what we choose, we will be using the printer with Caldera.
