I am upgrading the SONY TRV30 I have had for a decade. I have felt that the camera has been limiting the quality of my footage for several trips.
I'm looking at the Sony CX560 and an L&M Bluefin (Standard). This seems to be a fairly popular pairing, though I'm not sure if the 560 is really just a new version of the 550?
I have a few questions I would love to get input on.
 I can't quite ascertain if it is compatible. It has been a long time since I purchased my olde Dolphin Pro housing with a LANC connector.
 With my current camera I used lights only rarely - what can I get by with? Or am I entering a whole new world and I'd better get decent lights?
 I have been using Final Cut Express 4. I understand there is an intermediate step to working with AVCHD from this camera. Should I be thinking about an upgrade to this new iMoviePlus, I mean Final Cut X when working with the CX560 footage?
