I use AirVPN. It's reliable and I like their vpn client Eddie, but there are a few things you should know. Google blocks traffic from all of their Dallas servers, about 20% of their us based servers. Also, a few web hosting companies block AirVPN traffic, at least on the servers I use, including GoDaddy. I can't access the Linux Mint forums while on AirVPN either. Every day or two I have to disable the VPN to access a site, which defeats the purpose, IMO.
One good thing about AirVPN is that they have sales often. But I would try a week now before committing. Reliability has been top notch and they have a lot of servers.
Edit: I use port forwarding for bittorrent and it was easy to set up. You log in on their website and choose a port to forward for your account. I'm honestly a novice at networking and I figured it out using these instructions.
