42G Lighting Recommendations

[JHG]

Here's my 42G tank. I'd prefer to use a retrofit or whatever else works best on the canopy portion of my tank. I used to have a few standard plant and aquarium bulbs for the tank when it had live plants (freshwater) and in the picture below and using a 20" bulb as it created a nice effect with the African cichlids coming out of shadows, etc. I'm leaning towards VHO setup and hoping to keep mostly soft corals. Any decent recommendation would be welcome. Looking for most cost effective setup. Anyone use DIY kits from AHSupply?
