I have a 9400 (traded up from 8900-when the 9400 came out). Love it, especially the HP needle plate and foot....stitch with that is perfect....the machine is quiet, the pull-out light is very helpful for these old eyes. I do not like the Accufeed Flex system....I have the 6600 and prefer the walking foot on that. The quarter inch foot that comes with the machine is not as accurate as the one I purchased, the Janome clear view quarter inch foot.....All in all, though I am happy with the machine.
