I really really disliked (hated) my Janome 6500 although many others loved it. Mine was a problem right from the beginning (company finally replaced it). The bobbin case would jam, rattle and jump (finally found out that there is a wick hole under the case that dries out and needs a drop of oil once in a while although this is not mentioned in the manual and my dealer seemed to know nothing about it). It hesitated and balked starting and stitching over seam junctions, hated thicker layers and wouldn't feed fabric in evenly. It clearly should have been painted yellow! The replaced machine was better but still had some of the same issues. I finally got so fed up with it that I sold it on Kijiji for $500 (paid $2000) and bought myself a lovely Juki Exceed 600.
