The only issue if you decided to go this route, would be the software - Oxygen. Kodak owned, it might be difficult to come by and I'm not sure you'd get the best out of the Creo, if you used 3rd party. This unit includes the software, another listed does not; that slight $$ saving between the two would be the difference between a brick and a Ferrari.
Additionally, the Creo no longer has service assistance, so you'd need to be stocked up with parts and ready to fix yourself - if that is daunting, probably best to go with one of the new ones currently available.
We use four of these and four Epson 12000XL at work. The Creo is amazing - dial in the dpi to what you want and away you go.
