I have the 8900 and the 12000 and love them. I recently went to a sewing class and sat next to a lady who had a 9900 so I asked her how she liked it. She wasn't as pleased as she thought she would be. Missing acufeed and something else. She also has the 12000 and likes it much better because of the larger throat and bigger embroidery hoops. Now that the 15000 is out, my dealer says that he has lots of 12000's in stock from trade ins
