I just bought the Janome DC 2012 for a backup machine about 4 months ago. So far, I love it. The presser foot doesn't have that little extra extension to get thick things under, but I have made a tote bag that was quite thick and it really wasn't a problem, I was just used to it on my other machine. I really do love the machine, though. It is quiet and has done everything I have asked of it so far. I love the superior feed system (SFS) that helps prevent fabric from going down into the needle hole when you start a seam.
good luck in your hunt! I, too, had narrowed it down to a Janome and a Brother, but the Janome dealer gave me some perks that made me choose the Janome. That and the fact it came with the walking foot!
