The iPower grow light systems on eBay can be ordered wth cool tubes, air cooled hoods, etc.. pretty much completely custom grow light kits and even the best ones are less than 200$. Comes with a ballast (dimmable, digital 400, 600 or 1000), mh + hps bulbs, hood of your choice (cool tube, air cooled, open "wing, etc.)... I had to have my ballast replaced once but other than that, these lights work fantastic; all of my friends use them too, but I was the only one whom had to get a replacement but the people were very cool about it... they even sent me a new piece of glasss for my air cooled hood because the 1st one I ordered busted during shipping, so they probably lost more money than they made when I ordered a 400 watt kit from them. Their name is 'hpsgrowlightstore'; they have great deals on lights and theyre pretty decent quality in all honesty.
