Lb1121

Does anyone know if the LB1121 is still being produced? I am having a hard time finding this model for purchase. There are a few third-party resellers selling the modem at an extreme markup. I am setting up a failover network, and would like to use the POE model if it is still available. I am comfortable waiting a few weeks to order the modem if it will be back in stock, if not, I will move forward with buying the non POE model. Any assistance is appreciated.
