No. That machine is quite easy to service yourself. The only tricky thing is that there's a cable when you take the top cover off that you need to be careful with. The thread cutter can be persnickety, but only if you don't control your threads -- hold tails when you start sewing and stop if a tangle happens. There are two bottoms to remove. But if you can take apart a Roketeer and get it sewing again, you can service your own Juki. Just oil where metal rubs on metal. The timing isn't likely to go out. It's a pretty tough machine.
