Seyfi Kustimur is the owner and he is a great man. He has long been involved with Basketball in the Ankara, Turkey area and I highly recommend their Basketball Coaching Boards.
Here are some of the options you can get from them.
They were kind enough to send me some sample Boards and I love them. They come in different sizes and board strength quality so be aware of that. The prices are fantastic even when shipping is added. The shipping costs are not expensive as the boards are light and small.
The boards I received looked like this and I have included the prices they would have cost, including shipping.
