Need to light up a 6ft planted tank

Hi, I'm new to this forum. I need some advise on setting up the lights on my 6ft X 2ft X 2ft tank. The plants i gonna keep include high lighting requirement plants. My best option I've been told is to use 3 MH 150W at around 6500K with maybe a 2 Fluoroscent tubes blue light to make it look more pleasing. The price I've gotten is scary!!! Fully computer controlled $7000 and $3500 for manually controlled. Found a Dymax one new for $700. Anyone got advise on either getting a new cheap one or a 2nd hand better quality one? If you have any you're letting go of, please let me know too. Thanks.
