Juki makes a wonderful sewing machine, but I have read problems/and praise with HZL line.. You really need to read all the previews you can find.. (I did)..
I have an older Juki TL98E, that I would not give up.. It has the extension table, and wide harp..Heavy duty stuff here..Sure wish it had an auto threader, but alas. I'm so happy with the thread cutter!!
They say Juki drinks oil, so , OK, I give it what it wants. Keep it clean of lint, it will serve you well.
It all depends on what you want, I guess..
