My Janome cost 90.00 CAD and it was one day service. He wants to see it again this summer but I don't think he will. I bought some pressurized air for delicate computer parts and give the bobbin case a clean out every month or so. Unless it starts giving problems with tension and feed (which I know I can't fix) it will be here at home where I can see it and talk to it everyday.
I'd advise anyone with a new machine to take it in during the warranty period. Because you know how sticky companies can be if the machine servicing schedule wasn't followed!
