@mrbill0 in Poland, someone is selling hundreds of second-hand r6220's at 80 PLN each, which is like 20 USD or two wrt54g's.
Still, considering the tremendous jump from 802.11g's 54Mbit/s to two-antenna-802.11ac's 800Mbit/s, and from 100Base-T to 1000Base-T ethernet, I'd say it's more than worth the price.
And if you're building a meshnet, you may need that extra bandwidth in a few places
