    Riso GR2750: Questions on inks & drums

    Hello! I'm newly registered here after browsing for many, many months. I've found a GR2750 with three drums (teal, purple and black) for $200 locally and I've decided to go for it! I am interested in experimenting with the silkscreening/printmaking capabilities of these fun machines after owning and using the Riso Gocco for a decade.

    INKS: I know that the GR2xxx and GR3xxx drums are different in size and I'm concerned about finding the correct inks, too! I think there was a chart floating around here listing ink compatibilities but I can't find it now. Or, does anyone know what to look for to find the right ink for the GR2750? I can't seem to find the correct info I need.

    DRUMS: Yes, I see many of the (W) drums for the GR3xxxs, but has anyone seen the other GR drums (A4)? For a while I had an RN series and drums weren't available anywhere, yet now many showed up on ebay. In your experience, do I just need to be patient and they will show up, or are these things just not around anymore?

    I thank you all in advance. This is such a great resource! I did search for hours for these answers, but still didn't feel like I got the correct info I need. I appreciate your input.
