Hey Scott - I cant comment on the Breville which is the point of your post, so Im sorry :-)
But, I do have the EM6910 and I find it a great little machine. Its slightly noisy but you get used to it, sometimes on a Sunday morning you need to wait for the rest of the house to wake up before you can begin your brew but its not that much of a deal.
Its a big step up from the sub $2-300 machines on the market and you can get a decent extraction from it. I also have the EM0480 which is a decent grinder but I initially had problems calibrating the machine or rather, having to add spacers. I sourced from Bunnings as Sunbeam were willing to provide them but were much too slow, they are good on the whole but have suffered stock issues recently in terms of parts. I still think that I could do with a much better grinder for a more consistent grind and hopefully less clumping...
Ive had both for around 6 months and am looking to upgrade already, not because I need to but just because I want to. I could get away with using this machine for at least another year or 2 and the quality of my coffee and experience gained is fantastic. Training on a Synesso / Mazzer combo has given me a glimpse of just how far I can and want to take it (if and when the pocket ever allows it) ;-)
Id highly recommend the EM6910 but would definitely look in to a mini mazzer or a better grinder, depending how serious your home habit is.
