Recommendations for delicious oolongs?

I'm only just now at 35 getting into the complex world of tea and I've noticed there are endless varities, especially oolong. I make kombucha and drink tea straight, sometimes flavoring the kombucha with more sweet tea in f2 and recently I got some Se Chung oolong that was fairly pricy ($40 for 1 lb) for what I normally would pay for tea but wow, it seems worth it because the tea is delicious.

Just wondering if anyone also really likes oolongs and has any recommendations type or vendor.
