I can't recommend a specific stand myself. However, you can look through the official parts for the BX2450: http://www.samsungparts.com/Products/Parts_and_Accessories/LS24B5HVFH/ZA/Default.aspx
Perhaps there's a hacker community for alternative mounting systems, too? Not sure. Feel free to chime in community.

Does anyone know if it is possible to purchase a monitor stand for the above monitor? Its too low for me to work on and I'd like to gain some space on my desk too.
