I actually found a number of decent mid-grade cakes from odds and ends of vendors but also bought a lot of really low-grade and overpriced cakes to find those. And most of those good cakes are no longer being carried although here's a fun one they still have with unusual leaves. No well-aged or truly high-end cakes, but I did purchase some of the cakes I liked more than once.

I've had better luck finding surprisingly good blacks on Amazon such as a golden needle from Fullchea and a Ruby 18 that is much better than most direct from Taiwanese vendors.
