The D-Link EXO AC2600 router (DIR-882) has everything you'd expect and more for $150. (It's around £125 in the UK, and it's AU$350 on D-Link's Australian site .) It's a dual-band 802.11ac router with one 2.4GHz band and one 5GHz band, having theoretical speeds of 800Mbps and 1.7Gbps, respectively.
Affordable and fast with all the latest features; like MU-MIMO; beamforming; multiple USB ports and four spatial streams
Customizing your settings can take awhile; D-Link advertises support for 160MHz channels, but this router currently can't use them; Very low flash memory
