I also use private internet access (PIA). It is ~$45/yr IIRC. For one price you get access to all of their services on all of your devices(computer VPN, torrent proxy, mobile VPN). I have used it for years with no problems. When I first set it up, I had the router running everything through the PIA VPN. This was a pain (limited speed, a huge pain to connect to the house from outside, to do geo-relocation you would be running double VPN etc.). Now I just turn it on on mobile devices when required (public wifi or pretty much anytime I am out of the country). FWIW, I tried using the Toronto server while I was in Korea so my data was encrypted into NA, but it was almost impossibly slow, HK server was an order of magnitude (or two) faster. I had also locked up my phone account so it couldn't be accessed from outside of NA to enhance security but the trip got extended and I needed to transfer money in. Being able to geo-relocate to deal with that helped (although that also means my security is barely enhanced because it is so easy to get around).
There are a ton of these VPN services that are probably very similar. Make sure that the one you choose keeps no logs (nothing to subpoena).
Wait a sec, are you trying to keep your family in a private VPN or provide a layer of security/obscurity? I have done private VPN's before (one running on a router, another on a Windows Server) and they were kind of a pain, but it may be the best way to ensure complete security. I don't know if it is possible, but I would investigate selective VPN traffic if you are setting one up yourself (eg. traffic associated with banking servers goes through VPN, traffic associated with youtube/netflix and the like doesn't). You might have to do it as Firefox is VPN protected and Chrome isn't (or something similar). I haven't done this, but it would eliminate many of my problems with everything going through the VPN.
