As pictured, the stand is from Ergotron, see link below.
http://www.amazon.com/Ergotron-Triple-Display-Stand-Black/dp/B000E9VF1UComes with 3 Acer 22" LCD's, model P224W 1680x1050. I don't have the stands that came with these monitors.
Everything works and in good condition. Just need it gone, don't have the space for it anymore. Paid about $1,000 for this setup a few years ago. These are not currently connected to a PC, so if you want to test the screens you will need to bring something with a VGA or DVI out, such as a laptop.
Heavy and well made, you probably will need two people to pick up.
