I purchased my Janome from a dealer who then retired. So much for that
I purchased my BabyLock Tiara second hand and approached the Handi Quilter dealer out of town for service. He wanted me to bring it in, but gave me the number of another sewing machine repair shop in town and they came and serviced it in-house when I said I couldn't move it.
I'm not sure if Juki is the kind of machine that *only* a Juki repairperson can fix, but if that is the case, it isn't something I would buy unless I really couldn't live without that particular machine.
