About the metal... The person I spoke to told me that all of the internals on the machine are metal, with no acrylic, nylon, or plastic on the mechanical moving parts.

I am conflicted here because I trust Rocky's opinion, but covet a half way decent low cost sewing machine.

So far, the only major complaint I can find in all of the online reviews of the machine is that it is very loud and rattles a lot. It seems they skimped out on things to reduce the vibration.
