Currently there are several resistors that are our of stock at mouser. I am working though the list to cross reference some of the parts to ones that are compatible and in stock. In addition, the list doesn't contain the DIP sockets required for the ICs, which need to be added. Also there are two parts that seem to be only available from digikey. i'll need to see if there is something that can cross over with mouser. A good number of the parts are available from BGMicro.com , however, not all of them are....
