I have the W&W D9 and I'm scared to use it. I have a single bobbin and 3 needles for it. IF I can find a few more needles I'll give it a try. Most of the ones I've seen are black and the decals are pretty much gone as in my case or they've been turned into tractors. They look like a simple to use machine but I just have this fear I'll break the really hard to find needles. I got lucky yesterday and there were 2 needles in a tube I bought otherwise I would only have the single needle.
