I bought mine from Hamilton technology for $99. Seems quality, the model is SMS122. Here's the email I sent to the last person that asked: http://www.hamiltontechnology.com I'm installing it now. The quality seems good. It is on this page http://www.hamiltontechnology.com/special_sale.htm if you call them they will tell you they no longer stock it. You have to ask for Dave, who is very helpful. Adam
