Keep in mind that you will prefer to use the top quality mode for your clients. This way you will achieve the legenday quality of the ColorSpan. Of course ColorSpan at its slowest is most likely faster than two simultaneous piezo printers printing even in tandem. If you live in a remote area, you might also consider taking the service technician course. That way you can attend to your nice new printer and keep yourself, your printer, and your clients content.
Some dealers have more or better service technicians than others.
Ilford OEMs the ColorSpan. ColorSpan is also sold by Agfa, as the Agfa Montana. Thus select which is the best option for yourself. Again, ask local owners who already have a ColorSpan in their studio. ColorSpan people at trade shows last year have told me that if you skip the daily maintenance then it is not surprising that problems may arise.
