SID Printers same as challenger and Pheaton ( Made in China )
I dont know exactly how this peope are in service.
what I can tell you is my experience with SID or Challenger Printers.
They are good, fast printers, with good ink and a good RIP. you will have production and good quality. I have seem them work in the caribbean and central america. I just made a ink swap to a challenger in Hoduras ( SID+ wasatch+ sericol ink ). the press prints good. it has a seiko 510 print head. they are easy to use and cheap to repair. good ROI less than 3 months if you have the bussines.
I hope this helps
