I don't think you can go wrong with a Janome. I prefer the 6600 over the 6500 due to the accuquilt feed. The only difference other than that is that the 6600 has all metal bushings, the 6500 has plastic. I am looking at the 6300, like the harp space, has the needle threader and thread cutter which is super nice. It also has the 9" harp. If money is no option, why not go with the Horizion, it has the free arm, lots of stitches, etc., and the 11" harp is a huge plus.
