Alternative recommendation to Turris Omnia

Reviving this thread as I will be taking on this project soon. Should be getting the keys to my new property on the 9th of November where shortly after I'll be starting the work to set this up.

I have just signed a contract with my ISP Virgin Media for 1Gbps down and 50mbps up. Shocking ratio, I know but that's cable in the UK for you.

Do we have any solid solutions for this? The IPU system recommends above is rather expensive at 300 euros.
