I should qualify my statement. A lot of people have a low opinion of the Chinese amidol because it's very nasty stuff to work with.

That would be unfortunate.
As foul a concoction as it is to work with, I use it because the blacks it yields seem denser to me. It's worth it to me to put up with the bad things about it to get more dmax in my Azo prints. So my opinion is both high and low. But I'm obsessive about print quality and brook no compromise for the sake of convenience. And you certainly can't beat the price of the Chinese stuff.
If Michael Smith uses it his opinion of it is very high. He won't use anything that won't yield the best possible print.
