Where can I buy "Good Cook" equipment? Please help if you know! =)?

[LuvMe Dont EatMe VEG]

I owe someone a brownie pan 9" X 13" and the old one was Good Cook brand. I need to know where I can go buy some of those. I found a similar one on Ebay, but it was an 8" X 8". Please let me know if you know! And thank you! =D
