Well, I still want to go and look at a few more models but I saw a few yesterday and I really like the Janome 6600. I have had my Janome for a few years now and have never had a problem with it, other than this last event, but I honestly think that is my inexperience (being the first time I free motion quilted anything) not the machine!
My Mother also has a Janome 6500 and she has never had any problems with hers either. Which she uses with her Grace and it works beautifully.
What I really love is that it has a long neck area so I can quilt larger quilts and even use it on a grace if I decide to get one at some point. It also has tons of features, you can see the very long list here. It also has very good reviews. All the quilt stores I have called said they sell very quickly, when they get one in it is usually gone within the week.
I still want to keep looking at other models so I will be looking at a few more this weekend, but the hubby said we can go and look at the Janome this weekend.
I will be keeping my other Janome if I do get a new machine because this one weighs a beastly 24lbs! Plus mine will be for my Sweet Allie Kat when she is ready to learn to quilt like her mother, grandmother and great grandmother!
