I am also looking at the Janome 6600p and you can get a brand new one for about $1400. I think that $1100 for it being 5 years old is a little steep. I am a Janome worshipper so my choice would always be the Janome. Here's a link to a brand new one on Amazon.

I would let the seller know that her price is too high for a 5 year old machine
