The Orange Pi R1 Plus from Orange Pi is low cost Quad core Raspberry Pi Alternative. 
In this video I run  OpenWrt Network Router OS on the Orange Pi R1 Plus. As a cheap router the  Orange Pi R1+ is a good Raspberry Pi Alternative with 2 x 1GB network connections and the CPU and RAM to use them.
If you want me to make a video installing something else leave a comment.
