The price sounds very good if you have the space for the frame. The Juki is well worth it!
I have a 3 yr old Juki and LOVE it! I have a Little Gracie II frame but I don't use it because it just took up too much space.
Also, Pfaff has a 17" or 18" long arm that only cost $4,000. I tried it out and it seems like a really good buy, especially in price compared to others that size.
I personally like FMQ and don't think I am going to invest in a long arm.
