I've found complete setups on the net that almost made me cry. I've spent more than the cost of the full set-up they offer. And I'm using CFL's and 4' fluoros! (1) - 400w HPS light with MH conversion, (1 ea) 400w HPS bulb & 400w MH bulb, ballast w/ 10' cord, (1) - 4-sided reflector, and (1) - dual outlet timer for only $165 + S&H.
