The easiest off-the-shelf option would be a router running OpenWrt. IIRC, it natively uses dnsmasq, and the relevant blacklists can be obtained from here:
My own setup is DIY: a Debian box running Unbound (recursive DNS) with the RPZ blacklists from above. This gets rid of the upstream DNS service such as the ISP's completely, and prevents tampering or censorship.
