I used an Janome quilting foot (bought for my Elna, but she can't FMQ) on my 15 clone. No extraneous noise. Mine isn't as quiet up in the arm area as I'd like, but it seems to be getting quieter with use. That being said, I do my FMQ on my 301, but she was out of commission once so I had to use the 15 clone and the Necchi.
