sub £35 answer and crypto
For the tech inclined its pretty simple to build a secure DNS solution using a Raspberry Pi running raspbian and dnscrypt.
Add in isc-dhcp-server and if you wanna stay in the gui world use WebAdmin for config. Had this running for years now, moved it to Pi for massive space/power saving a couple of years back.
Also makes a great openvpn server and sixxs tunnel box too, they all run perfectly well concurrently with dns/dhcp etc.
Another plus is no DNS intercept from Virgin anymore.
