I've been using NordVPN for the last year and so far no issues to speak of. I think that it's around £80 per year and has servers all over the planet (not much use at the moment!). As always there will be some slowing of the speeds, but for my needs it didn't make much difference. If safety is more important than speed when travelling then a VPN is a no-brainer. You only have to be hacked/spoofed/whatever once for a whole lot of headaches to appear, so it's worth doing if away from the home connection.
