years ago i had a juki tl98q... loved it! but sold it with my quilt from when i left minnesota. just recently, i got a new juki tl2010q. i had been frustrated trying to fmq on my juki f600. the difference is like night and day and i can now fmq with confidence on the 2010q. i had bought both through ed reichert in phoenix
http://www.raichert.com/ . the service is excellent and their prices about $100 less.
