I have been looking for 18 months... on here, CL, national boards, etc. I have come to the conclusion that I will have to order one. I will just go with 12 feet since I have to order it.
I have a 7x2x2 that needs resealed that you can have if you want. Standard Oceanic 200G - it is really 210. It is drilled for a pair of 1.5" overflows and 1" returns. Free. It has the huge glass brace in the middle which is perfect for darker areas.
