Good news! I just found and bought one of these at one of my local aquarium stores that had 1 (very dusty) left in stock. $50! So arguably, this $1 sale is BS. The tank is normally sold for $130 with the top and light. So with the sale it is $40. I paid another $50 for the top, that leaves $40 for the light. Which is about what they sell these lights for. I should have just gone ahead and got the 75 gallon tank with top and lights for $175 on sale. But oh well.
usually those aquarium kits with their own tops and lights aren't the greatest. At least you'll be able to customize your lighting, and the 40 breeder is a good footprint to work with.
