I got them when I got my tanks, If you are in michigan there is a place that I got too that they have the best deals on tanks.
They have all kinds of tanks plus they can custom make tanks and they have all the accessories and food. Only thing is that they are open thursday, friday, saturday, and sunday, and they are only open a couple of hours those days. They even carry a small selection of fresh and saltwater fish. I got a 85 and a 65 gallon with stand and lids for around the low $400
The 85 gallon alone is like $127 out the door. They charge $100 for a 40 gallon at petco. I'm getting 2 180's with light and lid for like $650. (i might change my order to 2-240 gallon tanks, if he gives me a deal, I've been coming there every thursday and friday for like 3 month spending at least $75, hope he gives me a deal) Well here is the name of the place:
