Hi Nautilus...after diving with Maluku Divers many times I tried out Blue Motion earlier this year. Maluku Divers is top notch in every respect...some of the best guides you'll ever dive with, food, and accommodation and, if its in your budget, I'd say make that your top choice. I tried Blue Motion this last time to save some $$ and wasn't disappointed..while on a budget i'd definitely go back there again. They are located about 15 minutes from the airport like Maluku Divers, and are situated nearly right next to the "Twilight Zone" divesite. Guides are ok...I had trouble not comparing them to MDs, and I'd say the dive op is a good place to go if you one who likes to do your own dive and find things on one's own (as they'll let you do after seeing your skills). Personally, for muck diving and being a photographer I generally prefer a guide, but also like to look around on my own as well. Dive prices are very reasonable, $25 or less, and you could do a night dive any evening. For day dives, they do a two tank morning dive with the ability to out for one addition dive in the afternoon. There isn't a great variety of accommodation in Laha, but I stayed at a homestay that was very comfortable and clean within walking distance to the dive center. For meals, there are a lot of choices among local warungs, and for lunch you can eat a prepared meal at the dive center. Any other questions, feel free to pm. I can't speak for Blue Rose or Dive into Ambon as have never dove with them.
