Black Series (or CIG as they where known before all of the law suits) have a really bad reputation over here. Like really bad.
If this thread has a couple of comments about how crap they are, Shep and Ball will be getting letters from lawyers soon enough.
CIG made crap trailers and if anyone made that known publicly they threatened the forum owners with legal action and get the negative comments pulled offline.
I would agree with your comments about the quality of the canvas as one of the most important concerns for your local environment.
Black series are all made in China AFAIK.
Some light reading for you;
