If you are planning to just do softies and anemones, or just the anemones and clowns I would go with a nice set of PC's. No reason to worry about evaporation and heat with the Halides. Although if you want a pimp system go with the halides with VHO actinic supplemental lighting. It all varies in the long run. I myself have a 75 Reef of mostly softies, and anemones.
My Lighting consists of a Coralife Deluxe Aqualight 4 x 65 watt PC's two 10,000k and two actinic witha total of 260 watts for this fixture( you can get it for around $190.00 + or - ). Also I have a 48" flourescent double striplight with 2 x 40 watt actinics to a total of 80 watts. Not a lot of light but enough to get you by and the Zoo's, Cups, anemones, ricordea, colt, ect... love it. Then again I am in the process of upgrading to a lighting system recently purchased from one of my friends. It is a 350 watt halide 110 watt VHO system(retails: around $400.00-$550.00) that I'm sure will rock. I'm merely waiting until I have enough money to buy the VHO bulbs.
