Update! I have purchased and received the Juki Miyabi 350 J Longarm machine. In case anyone is interested, I purchased it from Quality Sewing and Vacuum located in WA although I don't live in that state or even close to it! However, they have provided excellent customer care, answered all my questions and I feel I have purchased a quality machine.
The table getting put together was a bit of a challenge - but we got it done.The table is very well made, and very, very sturdy.
The machine is a dream. It came with a loaded bobbin and after threading - we were just stitching along. It literally worked right out of the box. I plan on mostly using the manual mode but feel the precision mode will be awesome for ruler work as it is hard to move the fabric, the ruler and the foot pedal. It has a thread cutter as well - that is just a treat. I realize that only time will tell if I truly own a quality machine but I know Juki makes great machines and I really have not come across a bad review on this machine.
