The Cisco Linksys EA6500 is not a bad performer, and the matching WUMC710 media bridge adapter is by far the best of the bunch in terms of design and performance, and although it's expensive it does have a 4-port Gigabit switch. I still don't like the router's Cisco Cloud Connect interface, though.
D-Link's DIR-865L is one of the cheapest 11ac routers around, and it shows. It is very ungainly, and the DWA-182 USB client adapter is quite large, but cheap. When I was testing it, it played havoc with my SIP telephones, probably because of an incompatibility with the SIP ALG.
Netgear also has a matching 11ac USB adapter, the A6200, which has a peculiar rotating antenna that makes it a bit of a space-hog in a notebook.
