Looked through some grow mags quick for prices....Sun System 4 is a 150watt HPS in house ballast for $160 w/o bulb. You'll need a few fans the and some Dayton 4" or 6" Axial Fans would work good 6" are like $70 and 4" are like $50 and you can probably find those cheap on ebay. Buy a pair though. To upgrade your probably looking at about $250-300.
But you will need a way to bring in new air and exit the old air. I have a 2' x 2' closet in one of my bathrooms and I took the door off by the hinges and mounted some like home styrofoam insulation stuff about 2" thick I found out in my shed to make a door. Then I mounted 4" Dayton fans in the styro at opposite corners one as an intake the other as an exhaust. I keep a 250W HPS when flowering in this area and it cooled it well.
