I just bought a new Janome 6600 last Saturday. My local dealer will take your last machine in on trade. I had bought the 3160 from him about 14 months ago, so he gave me the full trade in value for it (the original price) I paid $1100 difference. I think I paid about $600 for the 3160, so was thrilled with the trade value he gave me. That would make it around $1700 then for the original price. It came with the extension table, all the attachments, knee lifter, cover, etc. The full deal.
I feel pretty sure I could have found it for a little less, but if I buy it somewhere else, he's not as likely to help me for free, which he does ALL the time. The excellent service they offer was worth paying a little more.
