Try for a used Janome 6600. Call Brubakerssewing.com and ask for Amy. She may have one, or put you on a list.
I don't work for them.....but I have purchased three machines from them. Many times your dealers have great sales on machines that they take to quilt shows. You may have more responses if you list a price range and specifications you are looking for. I own the Janome 6600 and 8900, love them both.
