I'll have to check out some of the subtitled ones. I don't like judging films if i can't follow what's going on. 
Is the image quality acceptable on most of them?

I'd suggest you first check out "Eight Diagram Pole Fighter". If you like that one, I would move on to "Bride with White Hair". They are both a bit like the King Hu films, but without the exceptional direction and philosophical grounding, though they both owe much to it.
Pole Fighter is more camp, while Bride is a tad more serious.
