Experience with the printer Canon PIXMA PRO-100S (or PRO-10S)

I am looking for a new large format printer (A3+)
Does anyone have experience with this one?
I'm interested mainly (of preference):
1/the problem of nozzles drying (small volume printing, not daily).
2/relation ink price/consumption
3/possible sw calibration
Alternatively welcome tip for other similar ones (Epson, HP)
thx for any advice
Peter
