i have the same dilemma. i purchased a cabinet and drilled my light and fan set up on the top. i have 4 43 watt cfls. i am waiting on seeds to begin using it. i used black electrical tape to cover any cracks where the light could escape. the ventilation system i built with a small fan and black tube vents is whisper quiet and all cost me about $100-$125 bucks for the entire setup. you will definitely want to keep the light very close to the plants so that they grow wide, not tall. the cabinet will allow for about 2 feet of height growth. just get a short strain like hindu kush and you should be solid
