When I moved over to 4/3 set up I opted for an Olympus EPL1 (I think) I got the Olympus housing, the kit lens, the 60mm and the 9-18. It was not long before I was regretting buying the set up wishing I had gone for something of a higher spec. I find it is important to have manual control for the settings, and now have the EM1/ Nauticam set up that is a great set up. The 60mm lens is great for macro (a real bonus in Bali) and can be easily used with one strobe (I use the sea and sea YSD1) for wide angle unless you are shooting in shallow water you will need two strobes. Ultimately it depends on how much you want to spend.... But unlike a previous comment I would not sit about waiting for a newer version of the EM1 to come out, new models are generally more expensive as well as the housings!
