Hi Guillaume,
I do still have the printer. I didn't see my private messages until 2 days ago so I didn't realize there was interest.
I got it at the end of March. Not sure what that means for the guarantee, but it's still sealed in the box so you should be alright.
I appreciate the offer, but I'm thinking more about 1600 (excl shipping), rather than 1100. That's currently the highest bid so far and I think a fair starting point for both parties.
That offer was a while ago, so if you are interested in that pricerange I can save it for you - assuming the other buyers don't reply in the near future.
Let me know!
