Thanks, all. Perhaps the friends with Home Hub v2 devices have been unlucky then; whilst I and them are indeed very happy with BT Broadband, their v2 Hubs have been relatively unstable whereas if I have to reboot my v1 twice a year it has been a bad year!
I'll do some research over the holiday, including to look at the KCorp products that a quick Google shows to be on the PC Pro A list, and then make my choice in the year.
Merry Christmas,
