VPN that will run through my DD-WRT router

What is a fast and reliable VPN service which I can run straight into my DD-WRT ASUS RT-N16 router? I am based in the UK and want to watch films on the American version of Netflix and I much prefer annual payments instead of monthly. 

I have looked around online but its much easier to ask someone from tek syndicate so excuse my laziness. Haha thanks

It works With anything with Open VPN, which pretty much all VPN providers use, Black VPN and VPNreactor are good, Black has a 7.50 euro (i think) plan for the ability to use servers in Canada, the U.S., Britian and the Netherlands i think, so id take a look into a few VPNs from this article

And go digging around from there.

Would OpenDNS Umbrella VPN (http://www.opendns.com/) be good option for me?

What would be the best VPN data client for the UK & Europe
