Long term the E-PL2 is the way to go. Yes it is the most costly but you get what you pay for. This is a camera even DSLR users are moving to as they want to "downsize". This is the best camera of group and there will be new lenses coming out for it all the time. If you go with the Oly housing but enjoy shooting wide angle you will want to add a Zen Pen Dome. As others have mentioned Wide Angle photo or video is going to require light. Lighting is a huge factor in taking your photos from ho-hum to artistic. Tons of options for lighting. The 9-18mm lens is the current best for WA.
Hope that helps.
