Please keep us updated! I am thinking about this exact machine, especially to try to learn FMQ. I have been sewing on a 50-year-old Riccar for years...and has made many quilts! I have only done SID with it. It sounds like a Mac truck, seriously! I have maintained it well, although it was recently giving me problems and I had it serviced for the first time. Come to find out it had a broken hook, a messed up bobbin case, and a few burrs, etc. Now it runs quite nicely.
My husband has been telling me for years to get a new machine. But I always tend to make due with what I have. Plus, I never took the time to research what I may want/need until this past week. The Juki looks like a great machine that would suit me. The features look amazing to me. So...I may take the plunge and get myself into the 21st century with my sewing.
Can't wait to hear how you do with FMQ.
