BT home Hub 4 vs Plusnet Sagecom Router

[#1]

OK - from ebay I can get a refurb BT Home Hub 4R for £20 - it is dual band where as the Sagecom isn't.  What's the opinion here - is £20 worth it for the few extra features?

The Home Hub 5 would be a better option with its built in VDSL modem, dual band wireless is worth the extra speed, less congestion if your wireless devices support it.

Ah, but can I get a 5 for £20?

Oh yes, so I can http://www.ebay.co.uk/itm/BT-Home-Hub-5-Wireless-AC-fibre-broadband-router-/111849017012?hash=item1a...;

  Reading up on Home Hubs and no easy way to change DNS - Grrrrrrrr

Having used the home hub 4, 5a & 5b I don't remember any problems with DNS settings.
First search on Google shows how to change setting from auto to manual............

You mean that first post where someone says how to do it, only for someone else to point out "BUSINESS hub, not HOME hub!"    https://community.bt.com/t5/Connected-Devices-Other/Manual-DNS-settings-please-for-home-hub-5/td-p/1...; ?
Most other Google hits say it isn't possible to set custom DNS, like https://community.bt.com/t5/Connected-Devices-Other/Changing-default-DNS-Server/td-p/191215/page/4

Reckon restrictions only apply when connected to BT ISP.
