Here we have some of the better priced routers on ebay. if you need a nice openwrt beginner router for your daily driver ide recommend archer c7 because of the dual band 5 ghz mode + the easy webflash option. pickup a c7 v2 router for under 80 dollars. if you’re good with linux the xiomi miwifi r3 option was fun too.
the cheepest more advanced option for a wrt router would be a a5-v11 $8 router with a usb hub and usb ethernet adapter.
a few pictures soon, maybe an adhoc writeup.
