I've been looking for a good 126660 (black or blue) for a while. The best of the lot, IMO, at the moment is the Noob v10, if it's still available. However, it has the A3235 movement, which is just a decorated copy of the 2836, I believe. I personally would not bother with one of those. Also, the Noob case back is painted, not Titanium.
I don't know anything about the other factories, but looking at the images of those watches, the dial print is not good, the cases are incorrect, as are the bracelets (wrong width at the lugs right down to the clasp). They appear to be an 116660 with a 126660 dial.
You can buy VR movements for an average of $100 USD from AliExpress and other markets. But swapping them out is the challenge, if you aren't capable of doing it and there is no one nearby who you trust.
I'm holding out for M2M ARF sales, or for VSF to tackle the DSSD.
