DCQ pots?
I see Hau Ying Chen has quite a few new pots. I would ask him if he has any via Facebook messenger. But his English is limited, so very clear wording will help, he won’t understand acronyms.
And if he does not have it he can almost surely get it, he is quite good at procuring things...
By the way his 60s pots seem to have undergone a massive price reduction, from over a 1000$ to 800something

Yes, I always ask, he’s got good contacts and knowledgeable sources. His 60’s hongni are a wee tinny, wish he had 120ml.
