@eschal...There are MANY options out there for VPN service; I can tell you only about the one I recommended; if you want to compare services, just Google something like "VPN comparisons" or "VPN ratings" to see what others say.
From my experience, the service I recommended has been fantastic. Again, it's easy to install (you do this once) on your computer and once you have an account you can use your credentials for other peripherals like an iPhone or iPad. I've never had any connectivity issues, though some browsers (namely Chrome) seem to run a bit slower when I'm logged into the VPN.
In terms of pricing, check out the link I provided. Again, there's a free service and a paid option. Can't remember if there's just one level of pricing or tiered but I remember that you can opt for a 6-month plan or an annual one.
