a 400 watt light will deffinitly work in an area that small. Your going to have to get good ventilation cause an HPS/MH light is gonna create alot of heat. You are going to need fresh air coming into the closet at all times. I personally grow under a 400 watt light and I have 6 plants no problem. A friend of mine did SOG and grew 15plants in the same area that i am growing my 6. My grow area is 3x3x6ft/WxLxH. If you can get an air cooled hood and some ducting I would recommend that to cut down on heat. Thats what i use in my sealed box. Xtrasun makes a great hood that is very inexpensive. I dont think that $260 is that great of a price for a ballast and hood that is used. A really good 400 watt digital ballast is only about $190 online and the xtrasun hood that goes with is is only $90. Lumatek makes a great ballast and their digital ballast do MH and HPS plus they dont flicker. Look up Lumatek 400 watt digital ballast and xtrasun 6in hood. The xtrasun hood is compatible with the lumatek ballast. Heat is going to be the biggest issue in a closet so trust me the air cooled hood is the way to go. a 400 watt light isnt usually that expensive to run. Where i live its costing me about $50 a month to run my light.
