I've heard good things about NordVPN too. With Netflix, it's an ever moving target as they keep adding more IP addresses to their list of blacklisted IPs. The big VPN providers, as you'd imagine, get targeted first.
On another note, the trick to getting them cheap is to watch out for special offers or deals. They usually pop up during the usual times (Black Friday, Christmas, Easter and so on). I pay around $30 a year for unlimited access. Most of the top providers have clients and apps for every platform imaginable. Some of them even have clients that run on routers that run embedded OSes.
The biggest of them all, PIA
, was doing a promotion a few days back for 2 years of access for just under $60.
