Hi I've owned a few EM6910's like Mal I'd be reluctant to recommend buying a used one personally for the potential problems I think $300 is too much. The first one I bought new and it makes a good coffee and lasted a good few years however the steamer died and I couldn't fix it and ended up buying another used one for under $100 that worked ok I did that again for $80 when that machine broke down. The 2 weak points seem to be the steamer and the where the portafilter lugs fit into seem to wear quite badly. I paid $400 a little over a year ago for my Expobar machine and grinder found it on Gumtree asking $600ish and made the offer to my surprise they took it I only asked to see it in operation. my advise other then trying to get something on this forum is to keep an eye on Gumtree ebay and the Facebook market place there are deals out there don't be afraid to make offers some people have had things for sale for months you've nothing to lose by asking.
