I have a Janome 6600 and love it! If you are looking to read or share information, there is a Yahoo group called Janome 6500 & 6600.
Otherwise you can converse with me...and we can work out things together. I'm not an expert by any means, but I own Janome, New Home and Elna machines..all made by the same company...and I love them all.
My favortie is the 6600 since it has the accufeed, start/stop and thread cutter.
This Christmas my mother bought me a Singer Futura 350 Embroidery machine. Huge leaning curve on this one....for the embroidering.
Happy sewing and quilting.
