I own a Fritzbox 3490 and it's very good. However it uses the Lantiq chipset which means no dsl stats and very limited stats via gui interface.
As you had put a nominal value of £100 pounds, is why I put the TP Link VR400 forward.
This uses the Broadcom BCM63168 chipset and has wireless AC, and is a combined modem router with Gigabit ethernet ports, and only costs £78ish pounds, from Broadband buyer.
