It's actually 3x slower than "ethernet". No one runs 10/100 in the home anymore with ethernet, it's all gigabit. Plus, those are under ideal conditions, the vast majority of people who actually use powerline adapters report significantly slower speeds. Plus, they fluctuate much more due to various loads on the electric system such as air conditioners, refrigerators, washing machines, etc.$70 bucks, "...with speed several times faster than regular Ethernet, the Comtrend PG-9172 G.hn is an excellent fix when you need to bring Internet to a place where Wi-Fi signal can't reach..." with a sustained 330Mb real world (CNET). I just researched this and given he has $200 i don't see why its not a good option for his use case.

Much cheaper than a AP.
Electric wiring is rated at 50/60Hz and is unshielded from other frequencies. It is not a good medium for data transfer. If WiFi is not viable, you are much better off with a set of MoCA adapters over powerline.
