Got a Riso GR3770 w/ SC7700 and works great for our one lonely black ink drum... but now on the search for some 'GR Color Drums A3'. They occasionally pop up on Ebay, often for more than the machine cost. Just wondering if someone had some tips for sources in Europe for these things or might be purging their own collection after upgrading machines?

Any tips are most welcome!

On a side note, if someone in Europe is looking for A4 Color drums, I have 3 to offer (just PM)... failed ebay purchase (thought they were GR W drums).
