PLA5456 compatibility with other brands of powerline adapters

Hello. I've been very happy so far with the performance of the PLA5456 (Kit), but the issue I have now is that I need a 3rd connection to another room. Unfortunately, the PLA5456 only seems to be sold as a kit of 2, and not sold separately. The least expensive kit I've found is $80 (Amazon), but only one single can only be found on eBay, priced for $70, which is just too much. Not knowing the protocols of powerline adapters, can the PLA5456 work alongside other brands TP-Link or Netgear? I'd much prefer to use another PLA5456, but I can't see spending another $80 for two, when only one is needed. Thanks.
