My Janome serviveman is the gentleman who sold me the machine. I was having a bit of trouble with the automatic threader. There was just a tiny screw that needed tightening. He has a bench fee of $25 but did not charge me because I bought the machine from him. Look at that threader, can you tighten the screw? ....but, agree with everyone else, call first, describe what needs to be done and maybe they can give you a better price....but $100, gosh, NO!
