I have seen 2 so far posted that were complete and running, and about as many besides yours with parts issues. I wasn't implying anything other than it seems that the parts issues are inconsistent so far or the couple I have seen had OEM parts subbed in without mentioning it.
Not implying anything about Facebook being better, just passing on what I have seen.
Like I said, either way I'm going to hold off a bit on getting one of these kits to see if the parts get better like the bigger saw kits have done.
