I think it is better to build your own cabinet, I did. I roughly spent about $1500 total including everything and chemicals. Although I have now upgraded with a water chiller for another $400. I bought a 2' x 3' x 6.5' tall metal cabinet from Staples for $260 delivered and put a 600 w HPS in it with a top of the line canfan air fan and filter and I built a drip system utilizing expanding clay pellets. I used a 1/2 drill that I rented at Home Depot for $22 and a 6" circular drill bit that cost $40 to drill the two 6" holes for the fan and intake air flow. For less money I basically built a better grow cabinet with more space and better internal equipment, plus I have a water chiller which is key to growing healthy plants. The internal temperature of the cabinet runs at 80 degrees with the lights on and 72 degrees with them off.
