You probably don’t need a VPN. (In personal contexts; work is different.) They’re really only good for porn (bypassing state ID checks), piracy (preventing your ISP from sending you nasty grams about downloading the latest Fast/Furious movie), and watching BBC shows from outside the UK.
But if you must use a VPN, I agree with Hynek that Mullvad is the least sketchy right now.
