The Asus RT-AC68U is an old but very well reviewed router. From what I've read, I think you'd struggle to find a better router at this price point.
For those that want something more powerful and 8 ethernet ports, the RT-AC88U is also available with the Bing Lee coupon (the Click and Collect price is just over $300). I decided the extra ~$130 wasn't worth it.
