I bought a lovely little bundle of sub stuff off eBay, which included an A3 GX7700h, which is great, but way too big.
It came with sawgrass inks throughout which leads me to believe it's been on them since day dot - and currently includes half full black, nearly empty cyan, and full of Y and M.
All inks expired, but colours still OK.
Looking to swap it for an A4 model as its just too big.
I'm based in Peterborough, but also spend some time in Hampshire/Surrey border so may be near to you at some point to swap.
