Note that it is the transmitter that has the older 2264 solder-blob technology to select the identifying address. The receivers have the newer "intelligent learning" technology that has built-in support for the older/legacy 2264 code method.
As I understand it, if you buy the ~$30 system, the 6 receivers have already been taught to recognize the address of the 2 supplied transmitters. In other words, someone at the factory pressed the one-button in the receiver to put the receiver into Learn mode. Then they pressed a button on the transmitter so that the receiver could Learn the transmitter's address. Then they repeated this for the other 5 receivers. Then they confirmed that the 2nd transmitter had its solder-blobs in the same pattern.
I think he's good to go and comes down to how fast he wants it vs. how much to pay. This configuration (two 6-channel transmitters and six 1-channel receivers) is available from many sources...Amazon, eBay, etc..
