usb network adaptor

Looking for a good, cheap deal (somewhere around Rs. 500) on a decent quality Gigabit USB-A NIC to be used with OpenWrt/pfSense. If you have a TP-Link UE306, I'd be interested but otherwise, anything decent in quality and has been tested with pfSense/OpenWrt setup also works for me.
