I started with diesel 6~7 years ago, my early pair were 71b, 71j. Back then 99% were MII, pricing was reasonable $250 +/-.
Then MII pricing start going up, and some non-MII showed up. In general, these were basic/simpler washes, solid blue color, not much detail, some mild fade. And you can get one less than $200.
Now, a good 50% (could be more) are non-MII. I agree with pryv75 that the quality are better with more detail, but pricing are much closer too.
