If you happen to live near Manchester, Curry's Outlet have one for £210. Pick up only. If I lived closer, I would have snapped it up ASUS ROG Rapture GT WiFi Cable & Fibre Router - AC 5300, Tri-band 4712900607741 | eBay
Mrsh can also work better with powerline backbone.

I have no information regarding specific bundles - best to keep an eye on this site for that. There is an option with ASUS to use Mesh Routers as part of the Mesh Network, they can be configured specifically for that mode disabling the regular Routing functionality. This may give you a lower cost avenue if routers become available. Look on the ASUS website for the list of Mesh compatible devices. Tks
Thank you. You reckon it's worth waiting for a bundle?. I do really want decent features!. And if openwrt is something possible on the same kit, then I'm listening keenly!.
