72" Lights from Aquatraders

[my2rotties]

Well the tank is cycling and we have decided to sell the two sets of 3 foot Tek LIghts and go with a 72" unit with the MH built into them. I see the $1300 lights from Coral Life and such but there is a company called Aquatraders and they have the same type of lights (have no clue whom makes them), for under $600 brand new. Here is the link for the lights.

I know generally you get what you pay for, but at half the price I am seriously looking at them.

Any insight would be most appreciated.
