Yes, I just left Manado. I dove in Bunaken and Lembeh and enjoyed them both. A vast improvement over Koh Tao! In Bunaken,
I stayed at Jonaths Resort and dove with Immanuels next door. I objected to paying rental fees for equipment and so looked for a dive center that did not charge for the standard scuba gear. In Lembeh, I stayed with Daniels and dove with Immanuels, which is the same outfit. They were nice people and I met some interesting fellow divers, especially a couple from Spain where the female had been diving almost everywhere and shared alot of what she knew about where to go and how to make the arrangements.
I particularly liked Lembeh, not specifically "muck diving" but just the relaxing atmosphere of a new (and almost empty) resort where I got a lot of personal attention and could work with he DM to pick when and where I wanted to dive. The Pegasus fish in particular was entertaining...poor guy..imagine having to go through life looking like that!
