Dave - I bought the GS VFD from Automation Direct a few years back. It works well, but is pretty noisy. I bought a line filter, but haven't installed it, but probably not a bad idea.
>From what I learned from installing the GS, I would consider some line filtering if you bought a chinese VFD. I want to say there was a thread on this mailing list quite a while ago regarding it, but I don't recall now. If you get a chance, search the mailing list or LInuxCNC forum.
