Depends on your definition of "high-end", while I personally stick with Mikrotik and Juniper gear a TP-Link TL-SG2008 is only $70 and gives you 8x1GbE ports and support for 802.1x just fine. For wireless you'd use WPA-Enterprise, which is pretty common on most consumer grade routers (for some reason), readily accessible on anything you can install OpenWRT on, and then on prosumer stuff like Ubiquiti AP's.
