 My tank is 24" deep and is SPS dominant.  They are 2-250 watt single end on electronic ballasts.  For an LPS/softie tank I would suggest 150 watt for your 20" deep tank, but you would need three to span 6 feet.  You would need to buy your lighting used in order to stay under $600.  Most of my LPS 
do not like the 250 watt halides and have to be placed off to the sides and in the shade.
