The advanced lessons do have something that isn't always easy to find: transcripts. Since written Cantonese is so rare, it's difficult to find natural spoken Cantonese with transcripts, and if these sorts of lessons came out on a regular basis, I'd probably still find it worth subscribing to. But without a regular schedule, with new material on at least a weekly basis, I'm still hesitating.

I signed up for the one-week trial on CantoneseClass101 and I've returned here in hope of better stuff, since the quality of their transcripts is abysmal.
