NEED HELP RELATED TO PRINTING MACHINE !!

Hello Everyone,

I am new to this website as I seen this website is very informative related to graphical needs.
As I am creative Designer from India planning to buy new or second hand digital printer to set up my own press either 4 colour or 6 colour printer. Does anybody can guide me which brand is best to buy and can work for long time with better quality and fast printing where I can use up-to 300Gsm to 600Gsm art board ..

Where can I find details in india about Printers like Xerox, HP Indigo, Konica Minalto, Etc ..

Thank You.

Awaited for your feedback.
