Late reply to this thread but i just stumbled upon it... So I purchased a 441 clone from alibaba about a year ago. it came right to my door, not a single additional fee i had to pay, no tariffs, import tax, nothing. I think it was $1200 or so including shipping (machine only). so far the thing has been flawless, build quality seems as good anything i've seen and honestly a lot better than buying a well used major brand version IMO. the name on it is JIANG LONG, and it's the long arm version.
I also bought a Global 217zz with cam reader a few years ago since i was unable to find a good 4-point zz machine anywhere (although i recently picked up a bernina with cam reader for $300 complete/first owner but I still prefer the Global). Similar experience with that machine, i think it was about $1500 to my door (machine only). I switch back and forth between it and the Bernina i picked up recently and the global is very close to as smooth operating as the bernina, and the global has 12mm width vs 6mm for the Bernina, plus it has a puller. For me, the extra features, and almost identical performance make it a winner. I need to/should sell the bernina but i haven't been able to yet, its such a sweet machine, 1 owner, came with manual and a bunch of cams for so cheap...
