need some advice on chosing a lamp... ++rep

i am planning on growing around 10 to 20 plants... i was originally going to get a 1000 watt hps but alot of people say that its actually better to get 2 600 watt hps,,, so wat do u guys think of this light??? it lets u upgrade to hortilux bulbs... Hydro Wholesale offers Wholesale Hydroponics, HPS and MH Grow Lights, HydroWholesale hydroponic Supp: Dual 30" Air Cooled Super Yield System 1200 watt (2 - 600w HPS)
thankss and + rep on any suggestions or advice!

With two 600's you can cover more area. the 600 is the best light vs power. At least for 110 power. LoL 2 1000w same thing but more bang in each light and more power use. my thoughts on it.
