Not the cheapest but by far the best I have used. I like the simplicity of their offering, the number of servers and more than everything the stability of the service.
I know by other people that support is good, I have never needed it.
OpenVPN + PPTP + Squid Proxies + some other features not common (as their own openvpn compile with password save feature enabled) make a very good mix.
