Large Format Color Printer

I'm looking for thoughts on large format printers.

We are looking to replace our 10+ year old HP Designjet 1050C. We would be printing presentation graphics, displays for trade shows, and other marketing materials from AutoCAD and other programs.

We have an Oce that we use for production work, so we would be using the new printer for graphics only except when we need a backup printer for the Oce.

Thanks in advance for any responses.
