At the moment I am looking at 400 watt SWITCHABLE GROW LIGHT w HPS Sodium + MH Halide - eBay (item 160253058948 end time Jul-08-08 14:54:00 PDT). They also have the same system with different reflectors ect. Does anyone have experience with the umbrella reflectors? Are they an improvement or just extra money?

I also ran into this linked in another thread.1000 Watt Sodium/Halide Switchable XtraSun I (ValueBrite) Reflector - Grow Light System. I was not even considering getting a 1k system becasue it was outside my spending range but $250 seems pretty cheap. Anyone have any experience with this site or know any catches with this particular system.
