well my advice is make up your mind on the coral first, because depending on wat type of coral u will have is going to affect your lights.As my experiences, make sure u buy the correct lighting the first time or u will waste insane amount of money.
here is an Eg.
for soft coral and some LPS
that doesn't require intense lighting go forcheaper PC
that has lower watts
(make sure you have both day light and atinic.)
, or anemone which need some wat intense lighting go for higher Watt lighting (this maybe not the best for anemone but it is enough to keep it alive)
If you are going for SPS
or clame or even anemones need very intense lighting such as ritteri go for MH
depending on where you buy those lighting, PC
can be range from $100-$400+ depending on the power and length.
is a bit expensive than PC
over all but the bulbs is cheaper than PC
is the most expensive one can range from $300-1k+
again depending on the watts and length and the number of light bulbs in it.
choose wisely, so u won't need to rebuy all your lighting later which might waste u way more money . HTH
